For a reliable clamping of connections of plastic material pipes (101) against axial forces, rolling members (24, 35) having peripheral asperities (25) are housed in a sealing joint (13, 23). Without biting exaggeratedly in the sections of the pipe, these members do not allow practically any deformation of engaged extremities (1, 107) at the connection point. A sleeve (110) is housed inside the male extremity (1, 102) and a ring (114) covers the projecting portion (7) of the sleeve containing the joint (13, 23). |
