ABSTRACT:
A combination lock for suitcases, luggage and the like of a simplified construction has a knob with three positions: a locking position, an unlocking position and a third position for changing the combination code of the lock. In order to prevent undesired entry into the code-changing position, a blocking mechanism is provided which is conveniently mounted on the knob. Normally the blocking mechanism can prevent the knob from entering its code-changing position, and during the re-adjustment of the code, the blocking mechanism can retain the knob in its code changing position. The lock is further provided with a latch member which allows a corresponding flap or hook to be pressed into locking position regardless of whether or not the number wheels are correctly dialed.
