A lock and method for suspending suture(s) from bone and providing a secure fixation of the suture(s) within the lock including a generally cylindrical outer shell having a tapered interior cavity or canal and tapered inner wall and a distal end, a generally cylindrical plug having a tapered exterior peripheral surface sized and adapted to be insertable into the outer shell cavity and to form a tight, compression holding or fixation of the suture to the lock, and the plug having a radially extending shoulder or protrusion, whereby insertion of the inner plug into the shell causes, the shoulder or protrusion to expand or snap outwardly and over the distal end of the outer shell and to lock the plug to the outer shell, whereby the suture(s) are locked into place within and to the shell, thereby providing rigid fixation and compression of the suture material.
