Abstract

L'invention concerne un raccord (4) présentant au moins une tubulure de raccordement (3), sur laquelle un tube (2) peut être enfilé. Le tube (2) est bloqué sur la tubulure de raccordement (3) par un manchon de serrage (36) en position serrée. La tubulure de raccordement (3) présente à hauteur axiale du manchon de serrage (36) une rainure de réception périphérique (17) pourvue d'une bague d'étanchéité (20) destinée à assurer l'étanchéité de la tubulure de raccordement (3) par rapport au tube (2) lorsque le manchon de serrage (36) est en position serrée. L'étendue axiale de la rainure de réception (17) est supérieure au diamètre de la bague d'étanchéité (20). L'invention se caractérise en ce qu'une section de réception périphérique (19) est réalisée dans un fond (18) de la rainure de réception (17), laquelle section est abaissée par rapport audit fond, au moins le diamètre extérieur du fond (18) de la rainure étant supérieur au diamètre intérieur de la bague d'étanchéité (20). On obtient ainsi un raccord (4) dans lequel un effet de ressort non souhaité de la bague d'étanchéité (20) est évité.
