Abstract

L’invention concerne une bride de serrage pour un harnais de câbles, comportant une pièce de verrouillage (15) dotée d’une mâchoire de verrouillage (17) et formée en saillie du côté de l’extrémité ouverte d’une partie de capot (12), et une partie (18) à verrouiller dotée d’un trou d’insertion (19) de pièce de verrouillage ménagé sur son côté périphérique intérieur et d’un trou d’insertion (20) de support ménagé sur son côté périphérique extérieur et formée du côté de l’extrémité ouverte d’une partie de corps (11). Un espace entre le trou d’insertion (19) de pièce de verrouillage et le trou d’insertion (20) de support est divisé au niveau de sa partie supérieure par une paroi de séparation (21). Une mâchoire d’enclenchement (23) destinée à s’enclencher sur la mâchoire de verrouillage (17) de la pièce de verrouillage (15) est formée au niveau de l’extrémité inférieure de la paroi de séparation (21) de manière à faire saillie vers le côté périphérique intérieur. Une mâchoire d’enclenchement (25) destinée à s’enclencher dans un trou de verrouillage (31) ménagé dans un support (30) est formée au niveau de l’extrémité supérieure de la paroi latérale périphérique extérieure (24) du trou d’insertion (20) de support, sous la mâchoire d’enclenchement (23) de manière à faire saillie vers le côté périphérique intérieur. Lorsque la mâchoire de verrouillage (17) est à moitié verrouillée sur la mâchoire d’enclenchement (23), la paroi de séparation (21) fait saillie du côté du trou d’insertion (20) de support pour empêcher l’insertion du support (30) dans le trou d’insertion de support.
