A compression ring with a mechanical connection in which a tongue-like member (14) in the male part (11b) is provided with an enlarged head portion (15) defined by transversely extending abutment surfaces (23, 24) forming a right angle with the lateral abutment surfaces (31, 32) of the enlarged head portion whereby the lateral abutment surfaces (31, 32) of the enlarged head portion pass over into the transverse end abutment surface (33) of the head portion (15) by way of a curved portion. The joints (50, 51) of some of the transversely extending abutment surfaces are subjected to swaging action to displace material in such a manner that the tendency of the male and female parts of the mechanical connection to move relative to one another in the radial direction is significantly reduced. <IMAGE> <IMAGE> |
