Title (EN) PUSH-FIT PIPE CONNECTOR WITH IMPROVED GRIPPING ASSEMBLY
(FR) RACCORD RAPIDE POUR TUYAU AVEC ENSEMBLE DE RETENUE AMÉLIORÉ
Abstract:
(EN) The invention relates to a gripping assembly (5) for a push-fit pipe connector (1) as well as a connector equipped therewith. Such gripping assembly prevents a pipe (4), once inserted, from being withdrawn from the connector. The assembly comprises a gripping device and a support structure (10). The gripping device comprises inclined teeth (11) extending radially inward, and inclined legs (12) extending radially outward. The support structure comprises an annular groove (15) for accommodating the legs of the gripping device. The groove is formed between an outer wall (18) facing an outer side of the legs, and an inner wall (16) facing the inner side of the legs. A width (x) of the groove, seen in radial cross section, is narrow near an entrance (E) of the groove and widens towards a base (B) of the groove.
(FR) L'invention porte sur un ensemble de retenue (5) pour un raccord rapide (1) de tuyau (1) à montage par emboîtement, ainsi que sur un raccord équipé dudit ensemble de retenue. Un tel ensemble de retenue empêche un tuyau (4), une fois introduit, d'être retiré du raccord. L'ensemble comprend un dispositif de retenue et une structure de support (10). Le dispositif de retenue comprend des dents inclinées (11) s'étendant radialement vers l'intérieur, et des pattes inclinées (12) s'étendant radialement vers l'extérieur. La structure de support comprend une rainure annulaire (15) pour recevoir les pattes du dispositif de retenue. La rainure est formée entre une paroi externe (18) tournée vers un côté externe des pattes, et une paroi interne (16) tournée vers le côté interne des pattes. Lorsqu'elle est observée en section transversale radiale, la largeur (x) de la rainure est faible à proximité de l'entrée (E) de ladite rainure, et augmente direction de la base (B) de la rainure.
