A series of keys partially encircle corresponding pawls having legs extending into a center slot of a slide bar, with a side slot at each side of the center slot, in which a pawl leg is placed, when the corresponding key is a part of the combination. When a key which is part of the combination is pushed, the corresponding pawl is turned, and its leg is moved from the side slot into the center slot of the slide bar. If a key not a part of the combination is pushed, the leg of the corresponding pawl will be moved into the opposite side slot. When the proper key combination is pushed, all of the pawl legs will then be in the center slot of the side bar, movement of which is then permitted, such as to unlock a catch, as of a luggage case. The keys are placed in pairs along a rocking bar, which is rocked by a restore key mounted thereon in alignment with the pawl keys, so as to move the down keys to an up position, or to move the keys of the combination to an up position, when pushed downwardly for setting the combination. For the latter purpose, the pawls are movable simultaneously by a lever, such as accessible on the inside of the luggage case, to move projections on the pawls away from dual sets of slots in the corresponding keys and permit the pawls to be returned, after the keys forming the combination are pushed down. The lock is particularly adapted to be installed between the pivoted ends of the handle of a luggage case.
