Patent ID: 7654588

Claim:
A pipe connection having a metallic clamping ring, which, for the purpose of connecting two metallic pipes that have been inserted one into the other, can be pushed axially onto the pipe that lies on the outside, whereby the clamping ring, on its inside, a) has an entry segment that narrows radially and conically, counter to the push-on direction, b) has an end segment that narrows radially and conically, counter to the push-on direction, which segment brings about radial compression of the pipes, in the assembled position, and c) has a center segment connecting the entry segment and end segment, wherein d) the center segment widens radially and conically counter to the push-on direction, wherein the entry segment is, in turn, divided into two consecutive partial segments that narrow radially and conically counter to the push-on direction, whereby the first partial segment, disposed on the opening side, has a greater incline than the second partial segment.
