A device to grip the end of a cable 12 or similar includes multiple wedges 14 defining an axial channel whose cross section is substantially different to the cables cross section. Preferably the cable has a circular cross section while the channel has a polygonal cross section, ideally square. Preferably the wedges are two cone halves, each half having a V shaped groove forming two sides of the square channel. The channel can have a constant or varying cross section. The wedges can be placed within a sleeve 16 with a conical internal surface matching the surface of the wedges. The wedges being pushed into the sleeve presses them into each other and causes the channel to constrict. Force on the cable in one direction would therefore tighten the grip of the device. The cable may be formed of a matrix reinforced with fibers, having a compliant core and/or coating. The arrangement can be held in a housing 18. |
