## Abstract

The invention relates to a pipe clamp, in particular an electric welding pipe clamp which can be mounted around a plastics pipeline, containing a saddle element having a connecting piece for a tapping unit or for the connection of an outgoing pipeline, straps to wrap around the pipeline, strap ends, wherein the strap ends have latching means, at least one latching area, wherein the strap ends are latched in in the latching area in order to fix the pipe clamp to the plastics pipeline, wherein the latching area has a tensioning element, wherein the tensioning element is arranged such that the tensioning element can be slid into a tensioning element groove.

## Claims

### Claim 1

A pipe clamp, in particular an electric welding pipe clamp, which can be fitted around a plastics pipeline, said pipe clamp comprising a saddle element having a connecting piece for a tapping unit or for the connection of an outgoing pipeline, straps for wrapping around the pipeline, strap ends, wherein the strap ends have latching means, at least one latching region, wherein, for the fastening of the pipe clamp to the plastics pipeline, the latching means of the strap ends are latched in the latching region, and wherein the latching region has a tensioning element, wherein the tensioning element is arranged slidably in a tensioning element groove.

### Claim 2 (depends on 1)

The pipe clamp as claimed in claim 1, wherein the latching region has at least one spring element, wherein the spring element exerts a force on the tensioning element and the straps are thereby constantly tensioned or continuously retensioned.

### Claim 3 (depends on 1)

The pipe clamp as claimed in claim 1, wherein the tensioning element has a locking device, wherein the locking device prevents the tensioning element from inadvertently springing out of the tensioning element groove.

### Claim 4 (depends on 1)

The pipe clamp as claimed in claim 1, wherein the pipe clamp has a locking pin, wherein the removal of the locking pin releases the force of the spring element onto the tensioning element.

### Claim 5 (depends on 1)

The pipe clamp as claimed in claim 1, wherein the tensioning element has unlocking tongues.

### Claim 6 (depends on 1)

The pipe clamp as claimed in claim 1, wherein the saddle element and the straps are configured in one piece.

### Claim 7 (depends on 1)

The pipe clamp as claimed in claim 1, wherein the pipe clamp has a latching region, which is arranged on one side of the saddle element and runs parallel to the center axis.

### Claim 8 (depends on 1)

The pipe clamp as claimed in claim 1, wherein the saddle element has two latching regions, which are arranged on both sides of the saddle element and run parallel to the center axis.

### Claim 9 (depends on 1)

The pipe clamp as claimed in claim 1, wherein the straps are mutually connected with a crosspiece.

### Claim 10 (depends on 1)

The pipe clamp as claimed in claim 1, wherein the unlocking tongues have latching means.
