A surgical apparatus (10) for tightening a strap loop (12) to a predetermined tension about split tissue portions includes a frame (16), an advancing mechanism for tightening the strap loop, a linkage mechanism which severs excess strap material not used in securing the tissue portions together and a control mechanism for controlling operation of the apparatus. The advancing mechanism includes a tensioning lever (18) and a gear mechanism. The gear mechanism includes a tensioning hub (36) and a clutch (38) which releases when the tension in the strap loop exceeds a predetermined value. The control mechanism includes a safety feature for preventing inadvertent activation of the linkage mechanism. A buckle and a method for use with the surgical apparatus is also disclosed. The invention is particularly contemplated for repair of the human sternum when the sternum has been split during surgical procedures. <IMAGE>
