ABSTRACT:
A duct for wiring comprises a plastic body member of U-shaped cross section and a plastic cover adapted to be received at an open end of the body member. The sidewalls of the body member are equipped with metal or plastic casing elements. The casing elements are clipped, preferably with detenting action, on the sidewalls of the body member by means of grooves and tongues on the respective parts. Another casing element may be provided on the cover and is adapted to be clipped on the body member proximate the open end. The base wall of the body member normally has no casing element and may accommodate a fastener for securing the duct to a support. A so-called connecting casing element may be provided in place of a plain casing element in order to assemble or group together two or more such ducts. In this event the connecting casing element connects the body members of two or more ducts.
