Abstract

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.
