## Abstract

A clamping ring has a flexible holding strap and a pivotal locking mechanism on the holding strap. A holding member has two apertures for receiving the holding strap. The apertures are arranged in reorientation points where the holding member is converted at each end into a foot part. A supporting strap engages at least partially on the holding strap and faces toward the interior of the clamping ring. The apertures are completely surrounded by the holding member. The holding member has a curved installation point or breakpoint in its middle bearing part between its two foot parts. The middle bearing part engages the holding strap and is arranged between the holding strap and a supporting strap. Between the holding strap free ends and the holding member, the supporting strap engages the holding strap and is connected with the holding strap in the area of their free ends. This clamping ring can be adapted to a plurality of different types of bodies, especially tubular bodies, and can be received even at points with cramped structural space. The holding strap, together with the supporting strap and the locking mechanism, can be moved longitudinally as desired along the curve of the clamping ring.

## Claims

### Claim 1

A clamping ring, comprising:
a flexible holding strap having free ends;
a pivotal locking mechanism coupled to said holding strap adjacent said free ends;
a holding member having a middle bearing part between foot parts at opposite ends of said holding member and having reorientation points between ends of said middle bearing part and said foot parts, said middle bearing part having a central breakpoint and two planar portions extending angularly relative to each other from said breakpoint, said foot parts having perpendicular web parts;
first and second apertures in and completely surrounded by said holding member, said apertures receiving said holding strap and being located at said reorientation points, each of said apertures being generally rectangular and being partially located in one of said web parts and partially located in said middle bearing part; and
a supporting strap at least partially engaging said holding strap and facing an interior of the clamping ring, said breakpoint engaging said holding strap and being arranged between said holding strap and said supporting strap, said supporting strap engaging portions of said holding strap between said apertures and said free ends and being connected with said holding strap adjacent said free ends.

### Claim 2 (depends on 1)

A clamping ring according to claim 1 wherein
said breakpoint is rounded; and
said middle bearing part engages and supports said supporting strap between said foot parts.

### Claim 3 (depends on 2)

A clamping ring according to claim 2 wherein
at least one connecting member engages and couples said supporting strap and said holding member, said connecting member having a strap part in said interior of the clamping ring and a snap-latch part extending around edges of said supporting strap and said holding member, said supporting strap being between said connecting member and holding member.

### Claim 4 (depends on 1)

A clamping ring according to claim 1 wherein
at least one connecting member engages and couples said supporting strap and said holding member, said connecting member having a strap part in said interior of the clamping ring and a snap-latch part extending around edges of said supporting strap and said holding member, said supporting strap being between said connecting member and holding member.

### Claim 5 (depends on 1)

A clamping ring according to claim 1 wherein
said breakpoint is curved.
