ABSTRACT:
A loose leaf binder is formed from two main parts, which have cooperating half-rings and are interconnected by wire links. The cooperating half-rings of the binder have a mating locking mechanism at their free ends.
The binder's opening is achieved through relative displacement, in longitudinal and transverse directions, of its main parts. A movable clip, placed at an end of the binder, prevents the relative displacement of the main parts when the binder is closed.
