An operating handle is fitted on a shaft to rotate between clamped and unclamped conditions. Part of the shaft is provided with opposed flats about which a shaft lock washer is non-rotatably fitted. The lock washer operates with a stop member to prevent rotation of the assembly and a nut is tightened on one end of the shaft to the required preload.
