A combination lock having dial-driven sleeves mounted in axial alignment on a shaft is provided with a shift member to move the sleeves axially out of coupling engagement with the dials for changing the combination of the lock. The shift member includes a manual actuating portion extending through an opening in the face plate of the lock, and when the lock is on combination, the shift member can be moved transversely to the axis of the sleeves to effect uncoupling of the sleeves from the dials by a camming action.
