A side-opening composite looseleaf binding apparatus for attachment to a backbone of a looseleaf binder cover. The binding apparatus comprises a one-piece molded plastic base having a planar floor portion, a stationary wall portion, a hinged wall portion separated from the stationary wall portion by a floor portion, and wherein the hinged wall portion includes an integral plastic hinge. A one-piece stamped metal finger or ring unit is provided having a strip portion connected to the hinge wall portion and a plurality of curved fingers or rings extending from the strip portion. In a closed position, the curved fingers have ends which are adjacent to and below an upper edge of the stationary wall. A spring member provides an opening bias for the finger unit and a locking member locks the finger portions of the finger unit in a closed position.
