Abstract

L'invention concerne un module d'assemblage à raccord constitué d'un raccord présentant au moins une tubulure de raccordement (3), sur laquelle un tube (2) peut être enfilé. Un anneau de blocage en plastique (26) fait par endroits saillie d'un manchon de serrage (36), lequel anneau est relié à la tubulure de raccordement (3) par encliquetage. L'anneau de blocage en plastique (26) est relié au manchon de serrage (36) de façon imperdable dans une position définie dans le sens axial de la tubulure de raccordement (3). Une pince de serrage à mâchoires de serrage (41) sert à fixer le manchon de serrage (36). Une nervure de serrage (43) de la pince de serrage est directement adjacente à l'anneau de blocage (26) dans le sens axial. Une autre nervure de serrage (44) s'étend à proximité d'une extrémité libre (37) du manchon de serrage (36). Une troisième nervure de serrage centrale (42), s'étendant au niveau d'une rainure annulaire (17) destinée à une bague d'étanchéité (20), présente une étendue axiale se trouvant dans un rapport approximatif compris entre 1 : 2,5 et 1 : 3,5 avec une largeur totale de serrage de la mâchoire de serrage (41). On obtient ainsi un module d'assemblage à raccord permettant d'éviter des déformations non souhaitées de l'anneau de blocage en plastique (26), tandis que le manchon de serrage (36) est serré de manière fiable.
