The present invention relates to a device for locking an object against a stop on a shaft, bar or the like. The device comprises a sleeve with a bore conformed to the shaft, and a ring movably connected to the sleeve in the axial direction and also having a bore conformed to the shaft. A member is arranged in the sleeve and adapted to act on the ring in such a manner that the ring is fixed in an inclined position relative to the shaft, and thereafter to move the sleeve away from the ring along the shaft so that the sleeve will urge the object against the stop.
