Abstract

A clamp for fastening an object in the form of a tube or hose, having an elongate clamp strap at each of the ends of which there is provided a radially outwardly projecting fastening leg, and having a rubber profile which is provided on the radial inner face of the clamp strap and which at least partially engages around each of the edges of the clamp strap by way of a lip. At least one first holding geometry is provided on the radial inner face of the clamp strap, and at least one second holding geometry is provided on the radial outer face of the rubber profile.

First claim

The invention claimed is:

1. A clamp for securing a tubular or hose-like object, having a clamp band, the clamp band being a flat metal sheet, the clamp band having ends, wherein on the ends of the clamp band an outwardly protruding securing member is provided in each case, and the clamp having a rubber profile which is arranged on a radial inner face of the clamp band and which at least partially engages around edges of the clamp band with a lip, wherein on the radial inner face of the clamp band at least a first retention geometry is provided and on a radial outer face of the rubber profile, at least a second retention geometry is provided, wherein the first and the second retention geometries are in engagement with each other in a radial direction (R), wherein the first retention geometry is at least one radially inwardly protruding projection which is provided on the radial inner face of the clamp band and the second retention geometry is at least one radial indentation which is provided in the radial outer face of the rubber profile, the at least one radially inwardly protruding projection engages in the at least one radial indentation, and wherein the at least one radially inwardly protruding projection is a plurality of radially inwardly protruding projections which are offset in a peripheral direction (U), wherein the radially inwardly protruding projections are formed by a bead which is embossed in the clamp band.

2. The clamp as claimed in claim 1 , wherein the radially inwardly protruding projections, the at least one radial indentation, or both the radially inwardly protruding projections and the at least one radial indentation extend on or are parallel with a longitudinal center axis of the clamp band.

3. The clamp as claimed in claim 1 , wherein the at least one radial indentation is constructed so as to extend in a peripheral direction.

4. The clamp as claimed in claim 1 , wherein the at least one radial indentation is a plurality of radial indentations which are arranged offset in the peripheral direction (U).

5. The clamp as claimed in claim 1 , wherein the rubber profile has in a region of the lips continuous recesses which extend in the peripheral direction (U).

6. The clamp as claimed in claim 1 , wherein in an axial direction between the edges of the clamp band and the rubber profile an air gap is formed.

7. The clamp as claimed in claim 1 , wherein the rubber profile is produced via a multi-component extrusion process.
