ABSTRACT:
An electrical plug includes a housing made of insulating material for receiving plug contacts, in particular, plug pins and coupling means for a feeder cable. The housing has a front face and a retractable spring-loaded release device received in the housing for movement between a retracted position, in which it is disposed substantially within the housing, and a withdrawn position, in which it projects outwardly from its front face. An actuation device is mounted on the housing for triggering movement of the spring-loaded device to said withdrawn position thereof by spring force, so that when the plug is received within a wall socket or a coupling having a mounting face opposing the front face thereof, the release device upon actuation will engage and push off from the mounting face to automatically effect or at least facilitate plug release.
