Abstract

La présente invention concerne un connecteur qui est équipé d'un corps de connecteur, d'un élément de verrou qui est mobile de façon sélective entre une position de verrouillage et une position de libération, et d'un élément de bague qui est capable de déplacer de façon sélective l'élément de verrou entre la position de verrouillage et la position de libération. Un corps de tuyau est équipé d'une section de réception de verrou au moyen de laquelle une partie de l'élément de verrou se met en prise. L'élément de verrou est équipé : de sections de verrou qui sont capables de se mettre en prise avec la section de réception de verrou ; et d'une section de connexion qui connecte les sections de verrou les unes avec les autres. L'élément de bague est doté d'une section de came et est en mesure de se déplacer grâce à l'opération de rotation de l'élément de bague vers une première position permettant de positionner les sections de verrou au niveau de la position de libération et vers une seconde position permettant de positionner l'élément de verrou au niveau de la position de verrouillage permettant à l'élément de verrou d'être soulevé et aux sections de verrou de se mettre en prise avec la section de réception de verrou du corps de tuyau. En conséquence, il est possible d'éviter un état partiellement ajusté ou une libération involontaire afin de garantir la sécurité, et la structure est simplifiée afin de réduire le diamètre extérieur.
