Abstract : The invention is directed to a security device which detects tampering with a secured closure. A fiber optic bundle is looped through a closure and secured at opposite ends of the bundle to a snap-together connector. An intermediate length of the fiber optic bundle surrounds the snap-together connector preventing access to its locking mechanism unless fibers are severed. After installation, light is passed through the fiber optics and a particular pattern is generated at a viewing end of the connector. Tampering with the closure will cause individual fiber optics to be disturbed or cut so that subsequent viewing of the fiber optics will generate a different viewing pattern than originally observed.
