Improved device for the electrical connection between catenaries and conductors, characterized essentially by the fact of being constituted by a tubular body, with its end parts corresponding to the inlet and outlet sensibly flared, two longitudinally extending flanges deriving from the body to define a cavity with its edges directed towards its interior, in order to limit its opening, said cavity being susceptible to partially housed and retaining the working thread, the body having on its flanks, between the tubular part and the longitudinal branches, respective depressions formed by roughly orthogonal planes.
