Locking system for cable raceways and cable raceways provided with such a system

摘要

The system (19) has a male locking unit (20) comprising clamps (21) whose height is extended transversely by a tab (26). A female unit (30) has a hole (31) formed between an upper edge and a lower edge on both sides of a reference axis (A). The lower edge defines a section in which the lower edge is at a distance from the reference axis greater than or equal to the height of the tab. The lower edge defines another trapezoidal section in which the lower edge is at a distance from the reference axis less than the height of the tab. An independent claim is also included for a cable channel comprising two telescopic sections.
