<p>A cable trapping device for an electrical apparatus (3) assembly box (1), the assembly box (1) having at least one connection window (9), the device being located in, or in the proximity of, the connection window (9), and allowing an insulated electrical conductor (8) to be slid in lengthwise through the window (9) in one direction and preventing removal in the opposite direction. The window (9) is provided with a fixed cut-away portion (12), which is disposed opposite to a moving cut-away portion (11) provided in the free end of resilient tab (10), there being formed between the fixed (12) and moving (11) cut-away portions a passage which, the lesser dimension thereof measured in the longitudinal direction of the tab (10) being smaller than the diameter of the electrical conductor (8), allows the electrical conductor (8) to pass in the direction of entry into the assembly box (1), by flexing of the tab (10) inwardly of the assembly box (1) and retains the electrical conductor (8) in the direction of removal from the assembly box (1) against a pulling force exerted in the direction of removal, by wedging of the moving cut-away portion (11) of the resilient tab (10) against the insulation of the electrical conductor (8). <IMAGE></p> |
