Abstract

A pipe connection comprises a connecting piece, a pipe and a clamping ring. The pipe and the clamping ring are made of a material having memory properties. An end of the pipe and the clamping ring have been reversibly expanded co-jointly and firmly and sealingly shrunk to the connecting piece by back shrinkage. Preferably the clamping ring is made from a cross-linked polyolefin by injection molding.
