Cable tensioning regulator comprising a lever (29) which can rotate associated to a base body (1) which, in turn, is connected to a cable (10) extending to the brake of the wheels. A spiral spring is arranged on the base and is connected to the cable, an extremity of said cable being connected to a mobile point, thereby avoiding an other body which rotates in the base in order to lock the cable. A box-like elongate body provided in the cable direction receives a carriage (45) to which are connected the extremities of said cable, the internal surface of the box being provided with ridged means. The carriage comprises elliptical parts (47) guided between each other and arranged on axes which are perpendicular to the carriage, said parts protruding side ways, said protuberances being ridged. The locking part of the cable is a lever which is hinged (35) to a portion of the brake body, presenting a rounded and toothed groove and nestable into a central window of the box to immobilize the cable. The elliptical parts can be only one single part and the ridged areas can be a tooth having a hooking function to the internal walls of the box.
