Abstract

L'invention concerne la liaison de chemins de câbles, un chemin de câbles se composant d'un chemin en treillis constitué de fils ou de barres métalliques, présentant des éléments transversaux en forme de U, et un ensemble de barres longitudinales reliant lesdits éléments transversaux, la partie avant d'un des chemins de câbles étant dotée d'un ensemble d'éléments permettant la liaison avec la partie arrière d'un autre chemin de câbles, les éléments de liaison étant formés de pièces de liaison comprenant deux parties : une première partie de fixation permanente, et une deuxième partie qui forme un guide pendant le montage, et un logement et un blocage de l'autre chemin de câble une fois la position de liaison finale atteinte. La partie extérieure du U formant le corps de la seconde partie est dotée d'un ou de plusieurs bords inclinés, et d'un ou de plusieurs logements pour le barres longitudinales du chemin de câbles à relier.
