Abstract
There is disclosed a theft-deterrent tag including a pair of elongated tag members movable between open and closed positions relative to each other. The tag includes a pair of frangible stress-sensitive containers each containing dye. Attempted unauthorized removal of the tag will cause the dye to spill onto merchandise positioned between the tag members. Each container is secured to a respective tag member and flexure of the tag member causes fracture. The elongate tag members are movably connected at one end portion and releasably locked at the other end portion to enable the dye to spill on the merchandise and to shield the thief from the dye. An improved magnetically releasable lock can hold the tag members in the closed position.
