Abstract
An elastomer packing 2 for male/female pipe joints is fitted with peripherally distributed, inserted or embedded locking elements E having a "seven" or T shape. The insertion of the male pipe into the female socket compresses the packing to establish a seal, and rotates the locking elements inwardly. Any withdrawal movements of the male pipe are halted by the counterrotation of the locking elements, whose beveled inner edges bite into the male pipe surface in a wedge like manner.
