Abstract: The invention relates to a connecting element consisting of a plate whose faces operate on either side of at least one automatically stripping connecting plug, in conjunction with an electrical conductor, in order to ensure the connection of the latter into the said plug. The plate consists of two faces through which two passages are provided, of sufficient dimensions to allow the conductor to pass through. These passages have two opposite edges arranged in the direction in which the plate is pushed in. The first edge is directed towards the free ends of the faces, in order to work in conjunction with the conductor when the latter is connected. The second edge which is opposite is provided in order to ensure the disconnection of the said conductor out of the plug, when the plate is withdrawn in the direction 18. An element of this kind can be used especially for connecting and disconnecting wires of telecommunication lines, on distributors or subdistributors.
