ABSTRACT:
A wedging device comprises at least two bodies which are movable in relation to each other, namely a first body having two diverging surfaces and a second body which is displaceable relative to the first body along one of its diverging surfaces. A heat-shrinkable casing, made for example from a tape, sheet or film of polymeric material, is arranged around the movable bodies of the device. When the device is heated, the casing shrinks, causing relative displacement between the first and second bodies and a consequent change in the outer dimensions of the device.
