ABSTRACT:
A ring binder (10) includes a ring metal (18) securable to a spine portion (16) of the binder. A spur eyelet (30) used for this purpose includes a post (32) one end (34) of which attaches to the ring metal. A plate (40) is formed at the other end of the post. Radiating outwardly from the underside of the plate are a plurality of concentrically formed spurs (50). Each spur has barbs (56) formed on an outer end (54) of the spur. To attach the ring metal to the spine, the spurs are pushed into the body of the spine. Thereafter, the barbs keep the eyelet from being pulled away from the body of the spine thereby preventing the ring metal from separating from the binder.
