A one piece molded polymeric ligating clip comprises a pair of curved jaws having a hinge at a proximal end and a latch at a distal end. The inner face of each jaw includes two rows of transverse ribs, with the rows separated from one another along a longitudinal center line of each jaw. The ribs of one row are staggered with respect to the ribs of the other row of the same jaw as well as ribs of the corresponding rows of the other jaw. Each rib includes a body and a pyramid which projects away from the inner face of its jaw and toward the longitudinal center of its jaw. The pyramid tip comprises a sharp apex which projects across the longitudinal center of its respective jaw.
