Abstract

L'invention concerne un dispositif de raccordement d'eau présentant un dispositif de déclenchement ; une goupille ; un manchon de logement destiné à recevoir le raccord de tuyau et présentant au moins un évidement pour la goupille ; et une bague de blocage présentant une première et une deuxième surface latérale. La goupille peut être positionnée dans une première et dans une deuxième position dans l'évidement de telle sorte que, dans la première position, un raccord de tuyau est bloqué et, dans la deuxième position, le raccord de tuyau est libéré pour être retiré. La bague de blocage peut être positionnée dans une première et dans une deuxième position de telle sorte que, dans la première position, la première surface latérale maintient la goupille dans la première position et, dans la deuxième position, la goupille peut être déplacée dans la deuxième position. Le dispositif de déclenchement peut être déplacé d'une première position dans une deuxième position de telle sorte que dans la deuxième position, l'épaulement du dispositif de déclenchement pousse contre la bague de blocage afin de déplacer la bague de blocage dans la deuxième position et de rendre ainsi la goupille déplaçable de la première dans la deuxième position.
