A method of manufacturing a part having at least one mechanically weakened area includes a step of producing a thermoplastics material part and at least one cycle of steps entailing forming a localized opening through an area of the part, heating the part locally by means of a heating probe so as to render the aforementioned area of the part plastic, and using a punch to modify the geometry of the area rendered plastic so as to delimit in the part a mechanically weakened area constituting a hole or hole precursor.

Electrical wiring trunking with a flexible hinge is reinforced to prevent impacts causing accidental opening of the cover section. The base section and the cover section are attached laterally by a hinge in the form of a flexible strip and respectively comprise a groove and a rib in the vicinity of the hinge and establishing a stiffening structure around the flexible strip when the cover section is closed.

Electrical wiring trunking with flexible hinge

Electrical wiring trunking has a lateral hinge which is reinforced in the closed position. The trunking has a back portion, a cover portion, a hinge defined by a strip, arrangements for stiffening the hinge, closure arrangements and a first internal rib projecting from the inside face of the cover portion on the same side as the closure arrangements.

An electrical wiring channel section covering accessory, for example an end-piece, has a covering part nesting over the channel section with ribs on the inside able to become embedded in a flange of the channel section, in particular in a bead thereon.

Accessory for electrical wiring conduit

A variable covering device for electrical wiring conduit includes two semi-rigid material portions attached to each other by an arrangement forming a hinge, wherein at least one variable aperture notch is formed between those portions near the hinge and the notch is filled or covered by an attached closure member adapted to enable angular adjustment of the two portions relative to each other by the hinge.
