Abstract

A disposable theft deterrent tag includes first and second elements that lock together through a portion of an item of merchandise to secure the tag to the item of merchandise. The first portion of the tag includes a first locking member having opposed teeth that are adapted to lockingly engage a second locking member that is carried by the second element of the tag. The second locking member is in the form of a stepped post that snaps between the opposed teeth to lock the post to the teeth. The tag may be unlocked by moving the teeth with respect to the post. In one embodiment of the invention, a portion of the body of the first element may be destroyed while moving the teeth from the locked position to the unlocked position.
