Abstract: The fixing device can be used to fix a wire (10) to a support member having a planar surface provided with at least two openings. The device is made of elastic sheet-metal and comprises a cut-out body which is bent into a U-shape and comprises a web (33) and two flanges (34) whose ends are T-shaped. At least one arm of the T-shape at each end is adapted to bear on the surface of the support member that is opposite the planar surface at the edge of an opening.

Abstract: A fixing device which can be fixed to a surface such as a ceiling and receive a perforated section comprises a plate for fixing it to the surface and a support for receiving the perforated section. The support has a wall substantially perpendicular to the plate and at least two claws with the same orientation which cooperate with corresponding perforations of the perforated section. The wall includes a precut locking lug which can be bent into another perforation and cooperate with an edge of that perforation to immobilize the perforated section against movement in translation.

Abstract: A wire cable duct includes a grid made up of wires of two different types, namely longitudinal wires which run longitudinally the entire length of the duct and U-shaped transverse wires disposed transversely to the longitudinal wires, from place to place along their length and appropriately attached thereto. The resulting trough-like combination forms three panels, namely a bottom panel and two side panels. The side panels include a longitudinal row of successive planar and substantially rectangular edge meshes which constitute upper parts of the side panels, each of which is defined between two facing flange portions of two consecutive transverse wires, and each of which includes at least one anti-flexing member to limit its flexing about an axis perpendicular to its plane.
