A lock designed for a bag having a flap extending over part of the top and part of the outside face of one wall of the bag, the lock consisting of a portion on the bag wall and a cooperating companion portion on the flap, the portion on the flap of the bag being so positioned as to overlie and mate with the portion on the bag wall, the two portions so constructed that the portion on the bag wall will be locked within the portion on the flap when the flap is pressed against the bag wall. When the two portions are locked in this manner they can be unlocked only by giving a 90 DEG turn to a locking knob on the outer portion.
