The present invention is an anchor for a thermally responsive ligature that deforms when heated. The ligature has an engaging segment for engaging the anchor with two clamping portions and a curved portion. The anchor is made from a thermally and/or electrically conductive material and has an engaging surface for engaging a curved portion of the ligature. The clamping portions of the engaging segment of the ligature pass between the body and the clamping component when the curved portion of the engaging segment is engaging the engaging surface of the anchor body. Then, portions of the clamping component can be moved towards the anchor body to reconfigure the clamping component so that the portions of the clamping component press the clamping portions of the engaging segment of the ligature against the anchor body and maintain the engaging segment of the ligature in thermal or electrical communication with the anchor body.
