A lock nut includes a nut body in which there is a drill hole equipped with an internal thread for a bolt body equipped with an external thread. In the nut, there are provided essentially axial cuts which extend to the drill hole over part of its length. Locking claws are positioned in the cuts. The locking claws bite when pressed against the bolt to prevent the nut from opening. The cut is of such a shape that a fulcrum is created for the locking claw, with the aid of which the locking claw can be levered away from the bolt.
