ABSTRACT:
Electrical connection device lockable in an open position provided with a plug having a cylindrical body equipped with internal contact pins and a power transmitting female element in the form of a socket or a coupler socket of an extension cord, and having a casing equipped with internal contacts and an external rotational ring that projects by extending beyond the casing and intended to lock and unlock the plug from or into the connection position. Coupling is accomplished via paired guide elements provided on the plug and female element by at least one first translational movement of the plug in the female connection followed by a rotation and a second translation until the closed connection position is obtained. The device is especially characterized in that the body of the plug is provided at its base with a locking tab that extends axially in the direction of the coupling and at a distance from the body so as to be able to pass above the locking ring during coupling, and in that the tab and the locking ring each have an opening, the angular positions of the openings and the longitudinal position of the opening of the tab being such that the openings get superposed during the second translational movement between the start thereof and before the final connection position so as to allow it to get locked, in this open position, still considered open, by any member that gets introduced into the openings.
