• a casing including two compartments, the casing further including two slots for intercommunicating the compartments with outside to allow respective passing of the pull tabs into the compartments;
• a number lock assembly including a plurality of number wheels rotatably mounted in the casing and a slide plate mounted in the casing and movable in a lateral direction in response to rotational movement of the number wheels, the slide plate including two engaging notches;
• a follower member including two legs releasably engaged with the engaging notches of the slide plate;
• and
• two push members pivotally mounted in the casing and each including a first end for manual operation and a second end with a locking piece and a lug, the lug being operably connected to the follower member, the locking piece being movable between a first position in an associated said compartment for engaging with an associated said pull tab of the zipper and a second position disengaging from the associated pull tab of the zipper upon manual pressing on the first end of the push member;
• whereby when the number wheels of the number lock assembly are not in correct code number for unlocking, engagement of the legs of the follower member with the engaging notches of the slide plate as well as pivotal movement of the push members are prevented to retain the locking pieces in the compartments for retaining the pull tabs in place,
• whereby when the number wheels of the number lock assembly are in the correct code number for unlocking, the lugs of the push members urge the legs of the follower member to engage with the engaging notches of the slide plate upon pivotal movement of the push members by manually pressing the first ends of the push members, thereby disengaging the locking pieces from the pull tabs and thus allowing removal of the pull tabs.
