摘要：A locking device () is fixed to a nut () and includes a coupling unit () insertableinto a hexagonal configuration () of a spigot end () at a reduced axial distance beingcoupled by mutually interpenetrable gears () with a stop unit () which axially slides in a
body () opposite to a compression spring (). The gears () are symmetric and are insertableinto each other with a predetermined elastic resistance by the action of compression orloosing torque. The device is embodied in one piece which is mounted by assembling withthe nut without affecting the spigot ends ().
