Abstract

L'invention concerne une protection contre le pliage de câbles préfabriqués (3, 4), comprenant un premier et un deuxième manchon (1, 2) qui passent chacun autour d'une partie du câble (3) et/ou d'un connecteur enfichable (4) et qui peuvent être assemblés dans différentes positions relatives. Selon l'invention, chacun des deux manchons (1, 2) est généralement réalisé sous la forme d'une pièce tubulaire droite pourvu d'un axe longitudinal central. Une extrémité du premier manchon (1) présente ici deux saillies rapportées, en forme de deux octogones réguliers (6) de même ouverture de clé, qui sont disposées de part et d'autre de l'axe longitudinal du premier manchon (1) et dont les axes de symétrie de rotation coïncident l'un avec l'autre et coupent perpendiculairement l'axe longitudinal du premier manchon (1). De plus, une extrémité du deuxième manchon (2) comporte quatre prolongements allongés rapportés (20) qui sont répartis en symétrie de rotation autour de l'axe longitudinal du deuxième manchon (2) et qui s'étendent chacun parallèlement à l'axe longitudinal du deuxième manchon (2). Les prolongements adjacents (20) forment deux à deux une mâchoire de clé (21) dont la largeur correspond à l'ouverture de clé de l'octogone (6).
