ABSTRACT A device for coupling to an object such as a pipe, par- ticularly for joining pipes together, comprising a tubular sleeve of which at least one end portion has positioned on it a collar of dimensionally heat-recoverable polymeric material, and a shape memory alloy driver. Recovery of the driver is arranged to deform one or both of the sleeve and the object into contact with one another. Recovery of the collar is arranged to fill at least partially the radial space between the sleeve and the object so as to provide relief from transverse strain imposed on the joint between the object and the device.
