A security system for connecting a cable to consumer articles, such as cameras, and the like, to prevent unauthorized removal of the articles from a predetermined area while being displayed in retail establishments on open shelves. The system in its most basic form comprises a device including a security cable and a threaded fastener. The security cable is passed through the threaded fastener, and then the threaded fastener is attached into the body of the article. The threaded fastener head has a special configuration and cannot be removed without a special key, thereby preventing the unauthorized removal of the secured property. The threaded fastener also includes a circular borehole through the entire length of the threaded fastener to allow the cable to pass through the opening, and a step is provided inside the borehole to stop the cable from coming off the fastener. Optionally, a reel, an alarm, or a fastener cover can be added to the basic system to make more difficult the removal of the security cable from the article.
