A ladder-type cable tray (10) for cables or the like, the ladder including one or more pairs of L-shaped side rail members (11) having vertical and horizontal sides, the vertical side (12) having formed therein a protruding spring tab (14) disposed above a socket (16); and one or more U-shaped rung members (22) formed at either end with a flange (23) enclosing a U-shaped opening and defining a folded edge terminating in at least one tooth (24), the folded edge having formed therein a slot (26) for engaging the spring tab (14), such that upon insertion of the rung member (22) tooth into the socket on the side-rail (11), the spring tab (14) is deflected laterally and returns to its position to engage the locking slot (26) in the rung (22) and lock the rung to the side-rail (11), the locked rung (22) forming a support platform for the cables in a rigid fashion.

L'invention concerne un chemin de câbles (10) en échelle pour câbles, et éléments similaires. L'échelle comprend une ou plusieurs paires de montants latéraux (11) comprenant un côté horizontal et un côté vertical (12, 18), un taquet à ressort saillant étant monté dans le côté vertical (12), au dessus d'un emboîtement (16); et un ou plusieurs barreaux (22) en U dont chaque extrémité comporte un rebord (23) présentant une ouverture en U et formant un bord rabattu se terminant par au moins une dent (24). Ce bord rabattu comprend une fente (26) dans laquelle le taquet à ressort (14) vient s'engager. Lorsque la dent du barreau est insérée dans l'emboîtement du montant (22), le taquet à ressort (22) est dévié latéralement puis se remet dans sa position initiale de manière à s'engager dans la fente (26) de verrouillage du barreau (22) et à verrouiller ainsi le barreau sur le montant latéral (11), le barreau (22) ainsi verrouillé formant une surface de support rigide pour les câbles.
