Abstract: A connector for supporting an object engages channels 4 in a track 1. The connector is retained laterally and guided longitudinally thereon. A locking element located between connector and track is moveable longitudinally to effect a locking.backslash.unlocking action. An object 40 to be supported is secured to one part 36 of a two-part connector in which the two parts have a quick-attach fastening 32,42 between them. One part 5 is connected to the track 1 and the other part 36 is connected to the object 40. The quick-attach fastening comprises a spring detent 44 and release button 7.

Abstract: Armor resistant to knife attack comprises a flexible sheet having a threat side facing a direction of threat and a protected side adjacent, in use, an area to be protected, and a plurality of armor plates attached to the sides of the sheet, the plates being grouped such that a first group attached to the protected side is in overlapping registration with a second group attached to the threat side, the registration being such that exposed regions of sheet on the threat side register with the first group of plates so preventing penetration of the armor through the exposed regions. By placing the overlapping groups on separate sides of the sheet, the armor is made more flexible than arrangements where the plates are mounted on the same side and are in engagement.
