Abstract

L'invention concerne un raccord (4) présentant au moins une tubulure de raccordement (3), sur laquelle un tube composite métal/plastique (2) peut être enfilé. Un anneau de blocage en plastique (26) est relié au raccord (4) par encliquetage. L'anneau de blocage en plastique (26) est également relié à un manchon de serrage (36), duquel ledit anneau fait radialement saillie par endroits. Une rainure d'encliquetage périphérique (24) de la tubulure de raccordement (3) est destinée à recevoir l'anneau de blocage en plastique (26), laquelle rainure est délimitée, d'une part, par un bourrelet périphérique (27), sur lequel l'anneau de blocage en plastique (26) est enfilé lorsqu'il est encliqueté sur le raccord (3), et, d'autre part, par une paroi de butée périphérique (28), contre laquelle l'anneau de blocage en plastique (26) vient buter lors de l'encliquetage. L'invention se caractérise en ce que la paroi de butée (28) est axialement en retrait d'un fond (29) de la rainure d'encliquetage (24), élargissant ladite rainure (24) au-dessus d'un cran (30), de sorte que, lorsque l'anneau de blocage en plastique (26) est encliqueté, un jeu (s) subsiste entre ledit anneau et la section en retrait de la paroi de butée (28). On obtient ainsi un raccord (4) à dimensionnement moins critique du collet d'encliquetage de l'anneau de blocage.
