ABSTRACT:
An assembly for forming a mechanical connection to an object, such as a tube within a hydraulic system, comprising a transversely heat-shrinkable shape memory alloy collar having an axially facing surface, a ring having an axially facing surface and a device for retaining the ring and the collar coaxially with respect to one another. In use, the collar is caused to shrink so that it engages the external surface of the tube. Force can be applied axially to the object through the collar by means of the ring.
