Abstract

A device for deterring theft of a protected article, including a pin and clutch for attaching the device to the article, with the pin and clutch being embodied in two components that are adapted to be locked together on opposite sides of a portion of the protected article to prevent unauthorized removal of the device from the article. One component includes a plurality of fragile elongated vials that fracture when flexed longitudinally, with each vial containing a detrimental substance that would damage the article if the vial were to be fractured while the device was attached to the article. The vial-containing component is so structured as to include a plurality of regions in which the vial-containing component flexes more easily in a predetermined direction than in other directions and regions, with the predetermined direction of easier flexing being different in different said given regions; and the vials are respectively disposed within each of the given regions of the vial-containing component such that when any of the given regions of the vial-containing component is flexed in the predetermined direction of easier-flexing for said given region, the vial disposed in said region is flexed longitudinally and fractures to thereby release the substance contained therein. The other component is so structured as not to flex when the attempt is made to pry the vial-containing component from the other component while the two components are locked together, thereby concentrating flexure forces resulting from said prying in the vial-containing component.
