A suture anchor comprising a one piece blank folded to form a body. The body has a floor, a first sidewall extending from one end of the floor and a second sidewall extending from an opposite end of the floor. A recess is defined by the floor, first sidewall and second sidewall. A crossbar extends inwardly from the second sidewall across the recess such that a free end of the crossbar is normally disposed distally of a transverse edge of the body. The crossbar is flexible such that when a distally directed force is applied, the free end of the crossbar is positionable in the recess. The free end of the crossbar is engageable with the transverse edge to limit the proximal motion of the crossbar from a proximally directed force.
