<p>Composite coupling devices for joining substrates comprising a preferably generally tubular heat-recoverable memory metal member, usually a radially heat-shrinkable member called a driver, and. a sleeve member positioned inside or outside said memory metal member, usually an insert, to facilitate connection to the substrate(s) are constructed in such a way that the degree of recovery is higher than that exhibited by similar composite devices in which both driver and insert are simple tubular members. In preferred embodiments the driver is constructed so that it exhibits a bending mode of deformation, optionally in addition to a tensional or compressive deformation. Typically this is achieved by forming the driver from pleated sheet, strip or wire.</p> |
