The locking system comprises a locking cylinder (23) provided with inner screw threads (24-26) conjugate with outer screw threads (22) of the nut (12), and in these two series of screw threads complementary axial splines are provided so that the locking cylinder (23) locks the nut (12) against rotation when their screw threads and respective splines are in engagement with each other. The locking cylinder (23) may be controlled by a cable (29). Application in the locking in particular of adjusting devices for table guides of woodworking machines and seat structures of vehicles.
