The invention entails a cable tie having an elongated body and a hollow receiving head. The receiving head is attached to the body at one end. At the other end, the receiving head contains a mouth opening. The mouth opening is sufficiently large to receive the opposite end of the body. Teeth are arranged on the exterior of the body. At least one locking arm with a lip is positioned at the mouth opening. Preferably, the arm should have two ends with a pivot point in between. The lip should be positioned on one side of the pivot point. The teeth and the lip are positioned to cooperate with one another so that the locking arm holds the body in position when the body is inserted into the receiving head. By applying pressure to the end of the arm opposite the lip, the arm may be pivoted so that the lip will disengage the teeth, allowing the body to be freely withdrawn from the receiving head. The locking arm and teeth may be constructed so that the cable tie may be tightened but not loosened when the lip and the teeth are engaged.

A one piece molded thermoplastic, preferably polypropylene, high security seal for coin bags has a locking socket body from which a flag extends on one side and a rectangular flat elongated shackle extends on the opposite side via an intermediate flat member which has a tear band there across for selectively separating the member into two pieces to facilitate removal of the locked seal. The shackle has several locking circular segment teeth in two parallel linear arrays on opposite edges of the shackle adjacent to a tamper resistant flange at the member end. A locking sheet metal stamped insert has two sets of tangs defining two spaced tooth receiving openings in a socket locking cavity aligned with shackle receiving openings in the body. The body receives the insert transverse to the shackle insertion direction through a cavity side wall later sealed with a flap formed in the seal body. The locked shackle precludes removal of the insert should the side wall seal be tampered with. The locked shackle forms a closed loop passed through an aperture in the bag folded neck. A hook on the intermediate member forms a tear band tab and engages the bag neck in the seal locked condition.

An apparatus for blocking the release of a slide fastener caused by the movement of a slider. According to the preferable embodiment, this apparatus comprises a pair of sliders, which are provided with a pair of ring-projections respectively, and a pair of engaging members as a blocking member for supporting and ensuring the interlocking of the ring-projections. Then, a pair of studs are provided at the engaging members respectively. When the sliders arranged reversely are moved forwardly to be contacted with each other for closing the slide fastener, the ring-projections are interlocked so that the eyes of the both ring-projections are overlapped. Next, each stud is pushed into the overlapped eyes from each side and engaged to another stud in the eyes so as not to be removed and not to be pulled out. Therefore, the release of the slide fastener caused by the movement of the slider is surely blocked. For allowing the release of the slide fastener, the base of either stud is cut and another side engaging member is pulled out. In so doing, the engaging members are disengaged from each other. Accordingly, the sliders can be moved backwardly away from each other for opening the slide fastener.

A one-piece tamper-proof bundling strap comprised of a head-end portion defining an aperture therethrough, the head-end portion being integrally connected to an elongated narrow body portion, the aperture in the head-end portion corresponding generally to the cross-sectional configuration of the body portion. The head-end portion and the body portion have a locking means integrally associated therewith for preventing reverse movement of the body portion relative to the head-end portion when the body portion is looped upon itself and disposed within the aperture of the head-end portion. The locking means is comprised of a plurality of serrations oriented along a portion of the length of the body portion and a plurality of projecting teeth members disposed within said through-aperture adapted to lock against the serrations when the body portion is looped upon itself and drawn through the aperture in the head-end portion. The strap is a one-piece unit constructed of a single, preferably brittle material which will fracture when exposed to tampering forces.
