Abstract

The invention relates to an arrangement (100) for connecting a first fluid-conducting component (110) to a second fluid-conducting component (120), more particularly in the exhaust gas line of a motor vehicle, having a seal (130), which seals the components (110, 120) at the connecting point, and having a band clamp (140), which encloses the components (110, 120) at the connecting point and attaches the components (110, 120) to each other. According to the invention, the seal (130) is formed with a tab (131), which protrudes at the connecting point after the components (110, 120) have been connected and is visible through a separation joint (141) of the band clamp (140). The invention further relates to a corresponding method for connecting a first fluid-conducting component (110) to a second fluid-conducting component (120).

First claim

What is claimed is:

1. An arrangement for connecting a first fluid-conducting component to a second fluid-conducting component, said arrangement comprising:
a seal sealing the first and second fluid-conducting components at a connecting point; and
a band clamp configured to enclose the first and second fluid-conducting components at the connecting point and to attach the first and second fluid-conducting components to each other,
said seal formed with a tab configured to protrude at the connecting point after the first and second fluid-conducting components have been connected, said tab being visible through a separation joint of the band clamp,
wherein the band clamp includes a single tensioning screw arranged at the separation joint such as to enable inspection of the separation joint.

2. The arrangement of claim 1 , wherein the first and second fluid-conducting components are components in an exhaust gas line of a motor vehicle.

3. The arrangement of claim 1 , wherein the tab is marked in color.

4. The arrangement of claim 1 , wherein the first fluid-conducting component has a connecting-point-facing end formed with a groove, said seal formed with a lug contoured to complement a contour of the groove, thereby allowing an exact positioning of the seal in a circumferential direction.

5. The arrangement of claim 1 , wherein the first and second fluid-conducting components are each formed with a T-flange, said band clamp embodied as a V-band clamp.

6. The arrangement of claim 1 , wherein the seal is formed as a single piece.

7. An arrangement for connecting a first fluid-conducting component to a second fluid-conducting component, said arrangement comprising:
a seal sealing the first and second fluid-conducting components at a connecting point; and
a band clamp configured to enclose the first and second fluid-conducting components at the connecting point and to attach the first and second fluid-conducting components to each other,
said seal formed with a tab configured to protrude at the connecting point after the first and second fluid-conducting components have been connected, said tab being visible through a separation joint of the band clamp,
wherein the second fluid-conducting component has a connecting-point-facing end formed with a mandrel, said band clamp formed with a lug, with the mandrel and the lug forming a rotation stop, thereby enabling an exact positioning of the band clamp in a circumferential direction.

8. The arrangement of claim 7 , wherein the first and second fluid-conducting components are components in an exhaust gas line of a motor vehicle.

9. The arrangement of claim 7 , wherein the tab is marked in color.

10. The arrangement of claim 7 , wherein the first fluid-conducting component has a connecting-point-facing end formed with a groove, said seal formed with a lug contoured to complement a contour of the groove, thereby allowing an exact positioning of the seal in a circumferential direction.

11. The arrangement of claim 7 , wherein the first and second fluid-conducting components are each formed with a T-flange, said band clamp embodied as a V-band clamp.

12. The arrangement of claim 7 , wherein the seal is formed as a single piece.

13. A method for connecting a first fluid-conducting component to a second fluid-conducting component, said method comprising:
forming a seal with a tab;
enclosing the first and second fluid-conducting components at a connecting point by a band clamp to attach the first and second fluid-conducting components to each other;
sealing the first and second fluid-conducting components at the connecting point by the seal such that the tab protrudes at the connecting point after the first and second fluid-conducting components have been connected;
visually checking whether the tab of the seal is visible through a separation joint of the band clamp; and
arranging a single tensioning screw of the band clamp at the separation joint such as to enable inspection of the separation joint.

14. The method of claim 13 , further comprising connecting the first fluid-conducting component to the second fluid-conducting component in an exhaust gas line of a motor vehicle.

15. The method of claim 13 , further comprising marking the tab in color.

16. The method of claim 13 , further comprising:
forming a connecting-point-facing end of the first fluid-conducting component with a groove; and
forming the seal with a lug contoured to complement a contour of the groove, thereby allowing an exact positioning of the seal in a circumferential direction.

17. The method of claim 13 , wherein the first and second fluid-conducting components are each formed with a T-flange, said band clamp configured as a V-band clamp.

18. The method of claim 13 , wherein the seal is formed as a single piece.

19. A method for connecting a first fluid-conducting component to a second fluid-conducting component, said method comprising:
forming a seal with a tab;
enclosing the first and second fluid-conducting components at a connecting point by a band clamp to attach the first and second fluid-conducting components to each other;
sealing the first and second fluid-conducting components at the connecting point by the seal such that the tab protrudes at the connecting point after the first and second fluid-conducting components have been connected;
visually checking whether the tab of the seal is visible through a separation joint of the band clamp; and
forming a connecting-point-facing end of the second fluid-conducting component with a mandrel; and
forming the band clamp with a lug; and
applying a circumferential force to the band clamp to cause a rotation of the band clamp until the lug of the band clamp touches the mandrel, thereby enabling an exact positioning of the band clamp in a circumferential direction.

20. The method of claim 19 , further comprising connecting the first fluid-conducting component to the second fluid-conducting component in an exhaust gas line of a motor vehicle.

21. The method of claim 19 , further comprising marking the tab in color.

22. The method of claim 19 , further comprising:
forming a connecting-point-facing end of the first fluid-conducting component with a groove; and
forming the seal with a lug contoured to complement a contour of the groove, thereby allowing an exact positioning of the seal in a circumferential direction.

23. The method of claim 19 , wherein the first and second fluid-conducting components are each formed with a T-flange, said band clamp configured as a V-band clamp.

24. The method of claim 19 , wherein the seal is formed as a single piece.
