Abstract
A fastener (30) for fastening a paper retaining binder mechanism (18) to the spine (16) of a binder (10) and remaining entirely concealed from an outer surface of the binder. The fastener includes a circular anchor plate (38) and a vertically extending attachment post or eyelet (34). The post is a truncated cone of uniform taper. The anchor plate includes a circumferential reinforcing lip (48). The fastener is secured to the spine by a number of spurs (50) uniformly spaced about the circumference of the anchor plate. The eyelet extends perpendicular of the anchor plate and the binder mechanism seats on the eyelet by an opening (26, 28). The upper end of the eyelet is then deformed about the opening to secure the binder mechanism in place.
