This is a connection device comprising an insulating case and it defines at least one housing and various connection openings and work openings, an electrical contact plate, a screw mounted in the housing, and clamping means stressed by the screw in order when required to immobilize together the conducting element and the contact plate. The case comprises means for retaining the screw inside the housing so that only the head of the screw is accessible from the outside through the work opening, the clamping means being completely insulated from the outside by the case, and rotation of the screw moves the clamping means translationally inside the housing between two separate positions at a distance from each other.
