A fastener for securing rebar rods that is a generally planar, elongated main body selectively deformed into a closed loop. The fastener can also include a head end integrally formed with the main body having a buckle and an opening. A tail end depends from the main body that has a plurality of substantially flat, spaced-apart, and staggered engaging members, or barbs. The rods are secured by folding the tail end around the rods and inserting the tail end into the opening of the buckle and twisting the tail end so that a barb engages an edge of the buckle.
