A pipe clamp has a tightenable clamp body and at least one spike strip arranged radially inwardly within the clamp body and slanted toward the axial center of the clamp body. The spike strip and a radially inner side of the clamp body delimit an acute angle therebetween. The spike strip has a first longitudinal edge provided with teeth projecting radially inwardly and slanted axially relative to the clamp body. The at least one spike strip has a second longitudinal edge supported in a radial direction and in an axial direction on the clamp body. An area between the at least one spike strip and the radially inner side of the clamp body defined by the acute angle is free of parts counteracting a bending of the at least one spike strip toward the radially inner side of the clamp body.

Pipe clamp, in particular, pipe coupling

A profiled clamp connecting two pipes has an articulated clamp strip having sidewalls and a transverse portion connecting the sidewalls and a tensioning closure around the clamp strip. A conical metal ring is arranged in the clamp strip and has a radially inner edge with teeth having free ends positioned on a circle with a diameter that is smaller than an inner diameter of the sidewalls. The conical ring has a radially outer edge resting in a bend between sidewall and transverse part. The first pipe has a widened end section with a conical transition and a radial flange engaging between the sidewalls. The second pipe has a smooth end section inserted into the widened end section. The outer flange diameter is greater than the inner sidewall diameter and smaller than the inner diameter of the transverse part. A seal rests between the smooth end section and the conical transition.
