ABSTRACT:
A two piece binder assembly with one piece adapted to be rivetted to the spine of a binder. The other piece is laterally slidable with respect to the fixed binder piece so as to engage the fixed binder piece and become, upon initial assembly, permanently secured to the fixed binder piece. The slidable piece is then movable between an open and a closed position by movement in a lateral direction which is perpendicular to the longitudinal axes of both pieces of the two piece binder assembly. The slidable piece is movable towards the fixed piece until the opposed fingers of the fixed and slidable pieces engage each other. At this point the slidable piece is secured to the fixed piece by the engagement of two hooked locking members with at least one hooked locking member becoming temporarily deformed until passing over the other hooked locking member and then snapping into place due to the resilient nature of the plastic material used so as to fixedly engage the two hooked locking members. Supplemental portions of the fixed and slidable piece slidingly engage each other to guide the slidable piece with respect to the fixed piece for aligned sliding of one piece with respect to the other.
