Abstract: A conduit binding system for use in restricted spaces of motor vehicles comprises an extruded body and a fastener for fastening the extruded body to a support panel. The extruded body can be of any usable selected length and is composed of a flexible material such as a plastic. The preferred plastic is polypropylene. The extruded body has a plurality of axial perforations that allow a length of the extrusion to be wrapped about one or more wires or tubes and to have its outer shape adapted to fit within a restricted space. The fastener attaches the body to a support member. The fastener may be of either wrap-around construction or may be a fastener fitted between the body and the support member. The fasteners are also preferably composed of a plastic such as polyethylene.
