Fastener for fastening together the ends of a length of steel strap wrapped around a package in a package strapper. It has a top and bottom. The top is above the section of a track where the fastening is established. The bottom is below the same section. The top is accommodated in a housing that pivots on the bottom on a hinge paralleling the track. The top comprises strap-shaping punches, a strap clamp, and a strap cutter. The bottom comprises a strap-shaping die mounted on a base and facing the punches. The pivot simultaneously constitutes a rotating shaft that drives all the fastener's moving parts by way of cams, eccentrics, or levers and rods.
