A heat recoverable connecting device which utilizes properties of shape-memory metal and method for making such a device is disclosed. The connecting device includes a body made from shape-memory metal capable of reversing between austenitic and martensitic states. The body has at least two arms cantilevered from a support structure which joins the arms. The arms are shaped so that in the martensitic state a substrate may be inserted therebetween to force open the arms with little effort. In the austenitic state, the arms close securely engaging the substrate inserted therebetween. Advantageously, the connecting device includes a second member which forces open the arms of the body in its martensitic state sufficiently to enable a substrate to be inserted in the device with zero force. The arms deform the second member when the body is in the austenitic state sufficiently to engage a substrate inserted in the device.
