Support and retaining device for wires and cables

A two-component device for supporting and retaining a cable or wire bundle (65) in a channel (60) comprises support part (10) with a support surface (14) in which is formed an elongate recess (16) for a cable tie (64). The upper part (10) lifts on to a lower part (12) and it secured to the floor (62) of the channel, by means of rivets (63) or the like. The support part has an integral tie bar (18) extending across the elongate recess. The lower part has a corresponding tie bar (30) extending across it, between opposed side walls (32) of the lower part. With the wire bundle in place, the cable tie (64) is passed around it and through the recess (16), passing under the respective tie bars (18, 30) and secured at (66) to hold the bundle in place against the support, at the same time holding the two parts of the support together.
