ABSTRACT:
A binding member having a pair of spaced ratcheted-surfaced posts which includes a bifurcated rim separated by an open groove, and extending from a binding member head. The binding member head is insertible into a counterbore in a paper sheets stack binding strip, the strip having an aperture through which the binding member posts are inserted. The rim includes a beveled ridge which passes through the strip aperture and snap locks into an exit portion of the aperture on a side of the strip opposite the counterbore. A finger-operated flat push disc binding/debinding tool is utilized to push and ratchet a pawl-containing locking collar on the posts and into a strip counterbore to clamp a paper sheets stack. An edge of the disc is insertible between the posts for breaking off excess length of a post extending from the strip and locking collar. The disc also contains a bifurcated bit for shearing from the posts. In the case of a thin bound stack of paper sheets, the open groove in the bifurcated rim accommodates a sheared pawl and allows debinding of the locking collar from the binding member.
