Fixing device for wire cable tray

Fixing device for wire cable trays (6) including on the one hand longitudinal warp wires (8) and on the other hand transverse weft wires (10), having a base (2) with a mounting face (16) by which it is mounted on the cable tray and fixing means (4;

• 34, 38, 38′),
• characterized in that it includes:
• at least one trough-shaped longitudinal housing (18) intended to receive a first wire of the cable tray and produced in the mounting face (16),
• at least one bearing surface (20) undercut relative to the mounting face (16), said surface extending perpendicularly to the longitudinal housing (18) and being disposed parallel to the back (22) of the longitudinal housing (18) at an intermediate level between the back (22) of that housing (18) and the mounting face (16), and
• at least one transverse cut-out (24) corresponding to each intersection between a longitudinal housing and a bearing surface, this cut-out (24) extending from one edge of the mounting face (16) to a longitudinal housing (18).
