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.

Abstract: A merchandise rack security device is provided which includes a plurality of elongated members depending from and slidable along a guide rail above articles of merchandise. In one embodiment, each member includes pivoted arms at the terminal end thereof which can be moved from a closed unlocked position in which they lie substantially along the axis of the elongate member and an open locked position in which they are substantially perpendicular to this axis. Each elongated member is extendable through a sleeve of an article, such as a garment hung on a hanger from a clothes rod, and by means of a control member located above the rod the arms can be simultaneously moved to the open position for each garment on the rack so that the garments cannot be removed therefrom. Similarly, the control means can be used to close the arms on the elongate members simultaneously so that any one of the garments can be removed from the garment rack.
