Le problème décrit par la présente invention est de fournir un raccord de câble pour une structure de piégeage susceptible de relier de manière fiable deux matériaux de câble orthogonaux tout en empêchant une réduction de résistance et/ou un glissement. La solution selon la présente invention porte sur un raccord de câble (1) pour une structure de piégeage qui est pourvu de deux plaques d'appui (10) et d'une pluralité d'éléments de fixation (20). Le raccord de câble (1) est caractérisé en ce que : les plaques d'appui (10) comportent chacune un corps de plaque (11), une seule première rainure (12) traversant la surface inférieure du corps de plaque (11), deux secondes rainures (13) s'étendant à partir de la circonférence externe de la surface inférieure du corps de plaque (11) vers le centre de la surface inférieure dans une direction orthogonale à la première rainure (12) et divisées au centre de la surface inférieure du corps de plaque (11), et une pluralité de trous traversants (14) pénétrant les deux surfaces du corps de plaque (11) ; la première rainure (12) devient plus profonde à partir de la circonférence externe de la surface inférieure du corps de plaque (11) vers le centre ; les secondes rainures (13) deviennent moins profondes à partir de la circonférence externe de la surface inférieure du corps de plaque (11) vers le centre ; et un trou de palier plan (30) est conçu en agençant les deux plaques d'appui (10) dont les surfaces inférieures se font face et tournées l'une par rapport à l'autre de 90 degrés, le trou de palier plan (30) étant apte à supporter, sur sa surface circonférentielle interne d'une manière plane, des matériaux de câble (B) entre la première rainure (12) et les secondes rainures (13) se faisant face.
