ABSTRACT:
A housing assembly for a theft-deterrent tack comprises a housing, at least one frangible vial containing a theft-deterrent substance disposed in the housing and a displaceable member supported by the housing for movement therein to cause fracture of the vial and for concurrently opening a theretofore closed portion of the assembly for egress of the theft-deterrent substance. The displaceable member has a first end portion, an opposed second end portion and an intermediate portion, the first end portion being in an interference movement path with the vial. The housing has a bounding surface having an opening therethrough, the displaceable member second end portion being resident in the housing bounding surface opening when the displaceable member is in non-fracturing relation to the vial. The displaceable member defines a passage therethrough opening into both of the first and second end portions thereof. A pin is disposed in the passage and, together with a locking member applied to a pin free end distal from the housing, is operative to secure the housing assembly to a garment to be protected.
