To simplify connection between electrical apparatuses, a connecting bar has been developed wherein the connection interfaces are flat. The connection devices comprise a conducting insert in a compressible insulating elastomer molded from casting, which is coated with a shielding. The connecting surfaces of the conducting inserts are located withdrawn with respect to the connection surfaces of the insulating support. When connection is performed, the insulating surfaces come into contact, compression is then performed enabling the interface to be made air-tight, while at the same time bringing the conducting surfaces into contact. The assembly is kept compressed by means of a central screw which is preferably associated with a blanking device of cover type for the connection surface not used for electrical connection. The connection solution according to the invention, in addition to speed, flexibility and reliability of connection, in particular enables the arrangements between electrical apparatuses to be simplified by a positioning tolerance, and in particular enables alignment of the pole-units to be connected.
