摘要

The invention concerns a duct comprising, along a generally U-shaped transverse section, a base (11) and two side wings (12). The invention is characterised in that said wiring duct has, transversely, here and there, to facilitate optional cutting up, zones with lower resistance, which, preferably extend at least over the whole width of its base (11), and which result, for example, from the presence of a hollow groove (15) on its inner or outer surface. The invention is particularly applicable to wiring ducts.
