Abstract: The set contains a central distribution box (20) having a plurality of severable electrical main terminals, for example connectable by a cable or by internal wiring to a distribution panel by, for example, a connector (22) or internal wiring. A plurality of identical adjacently located multi-terminal connection sockets (21) are located at the sides of the distribution box. The socket or receptacle terminals of the sockets (21) are internally connected to the main terminals by electrical connections on a conductor support plate.

Abstract: A multi-pole electric plug having two housing parts nested in one another is proposed, in which both housing parts are connected in the direction in which they are put together by means of a snap connector which locks into place automatically when the parts are put together. The snap connector has a protruding finger with a thickened snap head in the outer housing part and in the inner housing part has a passageway bore intended for the finger and having a protruding inner annular shoulder, which is engaged from the back by the snap head. Unintentional unlocking is prevented by a threaded segment of a screw extending through the finger, which when the plug is inserted is simultaneously screwed in as a screw securing means.
