New device for insulating the rails on the sleepers, characterized by the fact that the screws or bolts-lag screws that retain the rail in the usual way are fixed on the sleeper by means of an insulating cover internally threaded to receive the lag screw or screw-lag, and externally so that its thickness is substantially constant, in addition to ensuring a favorable distribution of the thrust forces, and because the surface of the external thread approaches that of the square fillet screw.
