ABSTRACT:
The invention concerns a nut provided with a locking element (4, 5, 6, 7), which by e.g. a screw (8, 9, 10, 11) can be urged radially against a screw thread. In order to provide a self-contained and easily releasable nut the locking element is arranged in a recess which, together with the element, is so arranged that at least a part (12, 13, 14, 15) of the element is deformed elastically when the element is moved against the screw thread. Thereby the element springs out of contact with the thread when the screw (8, 9, 10, 11) is released.
