ABSTRACT:
A locking nut has an internal thread intended to be screwed up on a thread on a shaft and includes at least one locking element which, by way of at least one locking screw, is adapted to be pressed against the thread in the shaft, thereby locking the nut against unintentional unlocking. The locking element is provided with a releasing device incorporating at least one screw arranged to be in threaded engagement with the locking element for subjecting the locking element to a radial pulling force causing the locking element to be lifted from engagement with the shaft thread after loosening of the locking screws.
