Abstract (en)
[origin: WO8203440A1] 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).
Abstract (fr)
Pour une fixation sure des raccords de tubes (101) en matiere plastique a l'encontre des forces axiales, des organes de roulement (24, 35) presentant des asperites peripheriques (25) sont loges dans un joint d'etancheite (13, 23). Sans mordre de facon exageree dans les sections de tube, ces organes n'autorisent pratiquement aucune deformation des extremites engagees (1, 107) a l'endroit du raccordement. Une douille (110) est logee a l'interieur de l'extremite male (1, 102) et une bague (114) recouvre la partie saillante (7) du manchon contenant le joint (13, 23).
