ABSTRACT:
The specification describes a lock provided with first locking means, second locking means and rotatable operating means for operating the first and second locking means. The arrangement is such that when the operating means is rotated in one direction from a first position in which the first locking means is in a locking position and the second locking means is in an unlocking position, the first locking means is moved to the unlocking position without disturbing the second locking means. When the operating means is rotated in the opposite direction from the first position, the first locking means remains in the locking position while the second locking means is moved to the locking position.
