An anchor for attaching an object within a tunnel extending through a workpiece such as a bone or a bone-like structure, and a method for using the same. The anchor includes a body and a plurality of barbs located in circumferentially spaced relation about the body. The barbs are formed of a material which may be elastically deformed from a normal configuration wherein the outer ends of the barbs extend radially outwardly of the body toward a configuration wherein the barbs are located generally parallel to the longitudinal axis of the body. A diametrical opening in the front portion of the anchor is provided for engagement by a length of cord-like material such that the anchor may be pulled into a bone tunnel, and an opening in the rear portion of the anchor is provided for attaching either a ligament, tendon or the like to the anchor, or for grasping a bone plug or similar rigid object attached to a free end of the ligament, tendon or the like.
