Abstract: A security device comprises a cable whose ends are engageable within a plunger. The cable is threaded around a door handle or other item to be secured and then, with the cable ends engaged therein, the plunger is slid within a housing for retention by a locking slide. Retraction of the plunger into the housing moves a slide upwardly. This movement causes a pivotally mounted striker to be flipped from one end position to another by an over-centre spring arrangement. In moving, the striker strikes a number of wheels each carrying a sequence of numbers. The wheels are rotated and a random number is displayed. If, subsequently, the plunger is released to release the cable, the wheels are struck again by the striker whereby the displayed number is changed. The number is changed again if the plunger is repositioned. The chance of the same number being randomly generated is insignificant. Thus, any opening and closing of the security device is immediately apparent because of the change in the number displayed.

Abstract: In sliding clasp fastening means comprising longitudinally extending mating strips and a U-shaped sliding clasp providing a channel fitting over the strips, the channel width tapering in the longitudinal direction of the strips and having adjacent the end thereof of greater width a pillar which fits between and holds the strips apart so that reciprocal movements of the clasp cause engagement or disengagement of the strips, the provision on one or both sides of the channel of means adapted to receive a tool operable to effect resilient separation of the sides of the channel to facilitate fitting of the clasp over the strips.
