Abstract

Selon la présente invention, la partie extérieure présente une paroi interne destinée à être attachée à un élément en forme de chaîne entre la première ouverture et la seconde ouverture et présente également une rainure de guidage située à l'intérieur de la paroi interne. La partie intérieure est raccordée à la partie de base sur le côté présentant la seconde ouverture et est prolongée vers le côté qui présente la première ouverture, et la partie intérieure comprend un bras mobile qui permet à l'élément en forme de chaîne de passer entre la paroi interne à attacher et une extrémité libre positionnée sur le côté qui présente la première ouverture. Le bras mobile est pourvu d'une partie qui doit être guidée et qui est guidée vers la rainure de guidage, ainsi que d'un cliquet qui fait saillie vers la paroi interne à attacher et dans l'élément en forme de chaîne. A mesure que la partie intérieure est déplacée depuis une position prédéterminée vers le côté qui présente la seconde ouverture sous l'effet de la traction sous tension de l'élément en forme de chaîne hors de la seconde ouverture, la rainure de guidage et la partie qui doit être guidée provoquent le déplacement du bras mobile de sorte à réduire petit à petit la distance entre l'extrémité libre et la paroi interne à attacher.
