ABSTRACT:
A releasable, reusable, tamperproof device for attaching an anti-theft monitor to an article of merchandise is disclosed. The attachment device includes a tack adapted to be passed through the monitor and the article and into a keeper. The keeper encloses a one-way fastener of the type having opposed legs defining surfaces for gripping the pointed shank of the tack. Compression of the opposed legs to a releasing position permits withdrawal of the tack. In accordance with one embodiment, the keeper includes openings through which rotatable key means are insertable for engaging and displacing the legs to the tack-releasing position. In another embodiment the keeper incorporates flexible diaphragms dividing the keeper into a pair of side chambers separated by a central chamber enclosing the one-way fastener. Pressurization of the side chambers deflects the diaphragms into engagement with the fastener legs and causes displacement thereof to the tack-releasing position.
In accordance with another aspect of the invention a releasing mechanism is provided including key means and apparatus for supporting the monitor in operative relationship to the key means and for rotating the key means to effect release of the tack.
