Abstract

The disclosure relates to a spring clamp, having a clamp band and a positioning device for pre-positioning the spring clamp on a hose end of a hose. The positioning device having a support band and a contact region, and the support band having. The positioner having a fixing means arranged at the end of the support band, and the support band having a retainer at another end of the support band. A web is formed in the support band between the contact region and the positioner. The support band has at least two regions in the region of the positioner, the first region extending from the web away from the clamp band and the second region extending substantially perpendicularly from the first region.

First claim

The invention claimed is:

1. A spring clamp comprising a clamp band and a positioning device pre-positioning the spring clamp on a hose end of a hose, wherein the positioning device comprises a support band, a contact region of which rests against an outer side of the clamp band, and the support band has on one side, in an axial direction (A) with respect to the spring clamp, a positioner having a fixing means arranged at the end of the support band and has at another end of the support band a retainer, wherein a web is formed in the support band between the contact region and the positioner, which web is oriented inwardly in a radial direction (R), with respect to the spring clamp, and the support band has in the region of the positioner at least two regions, wherein the first region adjoins the web in the axial direction (A) away from the clamp band and the second region adjoins the first region substantially perpendicularly, wherein at least one notch is provided in the region of the web, wherein as a result of the notch a clamping tab can be bent from the support band in the direction towards the clamp band, wherein the clamping tab engages at least in part around the clamp band in a radial direction (R).

2. The spring clamp as claimed in claim 1 , wherein the support band has a smaller extent in a circumferential direction (U) of the spring clamp than in the axial direction (A).

3. The spring clamp as claimed in claim 1 , wherein the web, the positioner and the retainer lie axially outside the spring clamp.

4. The spring clamp as claimed in claim 1 , wherein the web rests laterally on the clamp band.

5. The spring clamp as claimed in claim 1 , wherein the contact region has a bend in a circumferential direction (U) of the spring clamp.

6. The spring clamp as claimed in claim 1 , wherein the positioner has a third region which has a shorter extent along the support band than does the first region of the positioner.

7. The spring clamp as claimed in claim 6 , wherein the third region of the positioner encloses on an inner side of the support band an obtuse or right angle with the second region of the positioner.

8. The spring clamp as claimed in claim 7 , wherein the third region of the positioner can be bent around a hose end of a hose, and the second region of the positioner thereby rests in the axial direction (A) on the hose end of the hose.

9. The spring clamp as claimed in claim 1 , wherein the retainer engages at least in part around the clamp band of the spring clamp in a radial direction (R), with respect to the spring clamp.

10. The spring clamp as claimed in claim 1 , wherein the retainer has at least one retaining tab which is in the form of a shaping of the support band.
