ABSTRACT:
Selective device for electrical connection is provided with a plug with multiple contacts designed to engage with the corresponding contacts of a socket, while a safety disk and a complementary disk mounted pivotally on the socket are provided with openings designed for passage of the contacts of the plug and are arranged so as to be entrained in rotation by the plug when the latter is locked on the socket from an initial position which is locked by a locking system that is disengaged when the plug is introduced into the socket. The locking system only acts on the complementary disk while a locking mechanism is provided between the complementary disk and the safety disk in order that the safety disk can be locked in a plurality of pre-established angular positions relative to the complementary disk so that the safety disk can be given an initial position at will by acting on the locking mechanism.
