Abstract:
A ballistic projectile includinga body portion defining an internal cavity and having a surround around the cavity, the surround having a longitudinal, round peripheral, slide surface; a cover portion having a longitudinal, round peripheral, slide surface complemental to said slide surface of the surround to render the body portion and the cover portion longitudinally slidably closable onto each other to close the cavity and an annular abutting surface which is inseparably fixed to, is generally at right angles to, and stands proud of the slide surface of the cover portion; complementally arranged peripheral seats in the respective slide surfaces, and a resilient generally peripheral ring which is a split ring to allow a cross dimension thereof to be reduced/increased by compression/expansion, one of the seats being of sufficient capacity to accommodate the ring fully to allow the ring to be strained fully into said one seat to cause the ring to be flush with or shy of the corresponding slide surface to allow the other of the slide surfaces to be slid past said one seat accommodating the ring fully, to index the seat to allow the ring to relax to enter said other seat such that the ring bridges an interface between, and intersecures, the body portion and the cover portion, the annular abutting surface covering said interface and rendering said peripheral ring concealed and rendering the projectile unopenable from externally and thus tamperproof.
