ABSTRACT:
The security system generally includes an elongate tubular member provided with a row of spaced apertures and a locking member movably mounted within the tubular member and formed with a series of pockets. Elongate flexible guard members with enlarged heads at each end are passed through a closed loop portion of the article and the heads are inserted through a selected pair of adjacent apertures and into the corresponding pockets. Relative movement of the tubular member and locking member reduce the effective exit area and all heads are locked in the tubular member simultaneously. An electrical circuit is connected with an alarm device and with the various pockets. When both heads of the guard member are in a selected pair of pockets or both removed, the circuit is complete. When one head is in a pocket and the other is not, or if a cable is cut by a shoplifter, the circuit is open. The alarm device is arranged to emit a visual and/or audio warning signal when the system is in locked condition and an open circuit occurs.
