A graft fixation device comprising a sheath having a body that defines an inner longitudinal bore and a member for insertion within the bore. The sheath includes at least two projections movably connected to the sheath body by a distal hinge. The distal hinge causes the projection to pivot inwardly as the sheath is placed in a bone tunnel, and to be displaceable radially outwardly of the sheath body upon insertion of the member within the bore.
