ABSTRACT:
An electrical supply device including a conductor rail on which a sliding adapter providing a connection between the conductors of the rails and an user apparatus is readily positioned, the rail having an asymetrical profile with slideways situated in two different and parallel planes in which the adaptor, by means of a system of guides, may slide. The adaptator has a head carrying contacts, whose dimensions and geometry allow it to be introduced into the rail at an angle of 90.degree. to the longitudinal axis of the rail, and to pivot only in a given direction. Before pivoting that, the whole adapter is slidable along the rail and can then be locked in any selected position.
