Abstract: An accessory, called fixing accessory, designed to be fixed by elastic pinching, locally to wire cable tray includes, in meshed form, wires (11,12) of two different types, namely, longitudinal wires (11) and, set transversely at various spots along the longitudinal wires (11), U-shaped transverse wires (12), the assembly globally forming, as for a wireway, three panels (13,14), namely, a base panel (13) and two side panels (14).

Abstract: The invention is a coupling assembling first and second wire cable tray unit sections. The coupling is an elongate rigid strip divided into two arms with each arm provided with mounting means. The mounting means on the first arm alone rendering the coupling solid with the first tray unit section without permanent deformation of the mounting means. The mounting means on the second arm resiliently latching the second arm to the coupling without permanent deformation of the mounting means on the second arm.

Abstract: The invention concerns a coupling for assembling wire cable tray unit sections. It comprises two arms (55, 56). Means (57, 58) for mounting the first arm (55) can independently catch the coupling on the first unit section (51, 52). Means for mounting the second arm (56) on a second unit section (53, 54) comprise at least one resilient catch means (60) which can co-operate with a transverse wire of the second unit section (54) during assembly of the two unit sections. The invention also concerns a cable tray unit section comprising pre-mounted couplings.
