The nut (1) has an internal thread (5) for screwing it onto a shaft or axle and includes a locking part (8, 8a) which can be urged against the thread on the shaft by at least one fixing screw (9). Each locking part includes a release mechanism comprising at least one screw (10) in threaded contact with the locking part so that the latter is subjected to a tensile force in the radial direction, causing the locking part to be lifted away and disengaged from the thread on the shaft when the fixing screw is loosened. |
