Abstract

A profile clamp includes a profile strip and an annular sealing element, the profile strip having two tensioning heads which are interconnected by a tensioning element. Furthermore, a corresponding sealing element and a conduit connection assembly include a profile clamp of this type. So that the sealing element is held so that it cannot rotate on the profile clamp, the sealing element has a retaining lug which extends radially outwards and is held on the tensioning element.

First claim

The invention claimed is:

1. A profile clamp comprising a profile strip and a ring-shaped sealing element, wherein the profile strip comprises two tensioning heads which are connected together by a tensioning element, wherein the sealing element comprises a radially outwardly protruding retaining lug which is held on the tensioning element, wherein the retaining lug comprises a hook with a free bent-around end which encompasses the tensioning element in part.

2. The profile clamp as claimed in claim 1 , wherein the sealing element comprises at least one radially outwardly projecting projection which is arranged in the region of a recess of the profile strip.

3. The profile clamp as claimed in claim 2 , wherein the projection is arranged diametrically opposite the retaining lug.

4. The profile clamp as claimed in claim 2 , wherein the projection comprises an angled end portion which lies radially outside the profile strip.

5. The profile clamp as claimed in claim 4 , wherein the profile strip comprises two strip halves which are connected together by a flexible bridge element, wherein the recess is formed by a spacing between the strip halves which is bridged by the bridge element.

6. The profile clamp as claimed in claim 5 , wherein the radial projection of the sealing element is connected to the bridge element.

7. The profile clamp as claimed in claim 6 , wherein the radial projection of the sealing element is connected to the bridge element by the angled end portion.

8. The profile clamp as claimed in claim 1 , wherein the sealing element comprises at least one first radially inwardly projecting tab.

9. The profile clamp as claimed in claim 8 , wherein the sealing element comprises a second radially inwardly projecting tab which is at a spacing from the first inwardly projecting tab in the circumferential direction.

10. The profile clamp as claimed in claim 9 , wherein the first tab and the second tab comprise different dimensions.

11. The profile clamp as claimed in claim 10 , wherein an extent in the circumferential direction of the first tab and second tab is different.

12. The profile clamp as claimed in claim 9 , wherein the first tab and the second tab are arranged at a same distance from the retaining lug in the circumferential direction.

13. The profile clamp as claimed in claim 1 , wherein the sealing element comprises at least one radially inwardly projecting, elastically deformable finger.

14. The profile clamp as claimed in claim 1 , wherein the retaining lug has an open end that accepts the tensioning element, the open end established in part by a free end of the hook.

15. The profile clamp as claimed in claim 1 , wherein the hook has a free end, and the encompassing of the tensioning element by the hook is incomplete due to the free end of the hook.

16. A conduit connection assembly comprising a conduit end on which is realized a flange, on which a profile clamp as claimed in claim 1 is arranged.

17. The conduit connection assembly as claimed in claim 16 , wherein the flange comprises at least one depression in which at least one radially inwardly projecting tab of the sealing element engages.
