Abstract

[Problème] L'invention a pour objet d'empêcher toute séparation intempestive du raccordement dans un état verrouillé par un contact externe accidentel et a par ailleurs pour objet de maintenir de manière fiable un état relié ou libéré sans bruit de cliquetis. [Solution] L'invention concerne un élément d'insertion (1) comportant un premier module de cadre coulissant cylindrique (14) qui est monté sur la surface périphérique extérieure du côté extrémité d'insertion de l'élément d'insertion de manière à pouvoir coulisser dans le sens axial et qui, par le mouvement coulissant, peut recouvrir une rainure de réception (12) en provenance du côté extrémité de connexion, et un deuxième module de cadre coulissant cylindrique (15) qui est monté sur la surface périphérique extérieure du côté extrémité d'insertion de premier module de cadre coulissant (14) de manière à pouvoir coulisser dans le sens axial. Dans l'état de libération de mise en prise et dans l'état relié, en faisant coulisser le deuxième module de cadre coulissant (15) vers l'extrémité de connexion, l'extrémité avant du deuxième cadre coulissant, qui a été poussée depuis l'extrémité d'ouverture (22E) dans un espace d'ouverture, peut être poussée dans l'extrémité d'ouverture (22E) de manière à remplir l'espace restant entre l'extrémité d'ouverture (22E) et le premier module de cadre coulissant.
