Abstract: An anti-theft device for articles having some article body portion of lesser cross sectional area bounded by body portions of greater cross sectional area so that the smaller body portion can be lockably held within a passage and the larger body portions prevent removal of the article from the anti-theft device. Preferably, the anti-theft device can be used for cables and other devices having permanent non-removable enlarged sections, such as endoscopy cables.

Abstract: An equipment housing is secured against removal from a clamping assembly which embraces two opposing sides of the equipment housing. Plates are affixed to said opposite sides of the housing by an adhesive means arranged in a unique manner to rely upon its shear strength to prevent unauthorized removal of the equipment or housing or both. The various types of adhesives which may be used in connection with this shear strength locking device may include single part adhesives which consist of liquids of various viscosity, as well as amorphous materials, films and layered films which include various types of double-sided tapes. Another category of adhesives is the multipart material which may consist of two-part epoxies or two-part acrylics. For the most part, high-tack adhesives, which cure at normal room temperatures, are the preferred material.Cyanoacrylates and similar matrials may be used where rapid cure and adhesion of dissimilar parts is required.
