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 collar. After installation, light is passed through the fiber optics and they generate a particular pattern at a viewing end of the collar. If there is any tamptering with the enclosure, the individual fiber optics will be disturbed or cut. Subsequent viewing of the fiber optics will generate a different viewing pattern indicating that tampering has occurred. Author
