A loose leaf binder securing mechanism in which a rigid track is mounted to the exterior of one cover hinge strip with sliders positioned on the track prior to mounting. The sliders are movable along portions of the track between passageways in the track in registry with perforations in the hinge strip and the assembled sheeted material to be bound. Flexible binder posts are mounted to the binder opposite the said one cover hinge strip and pass through the perforations. Each slider has a hook member which is adapted to engage along a portion of the surface of the binder post associated therewith when the post is passed through its respective passageway and bent to lie along the length of the track. In one embodiment, the hook member of each slider is in disalignment with the passageways so that it is not possible to push a slider past its associated post where the post emerges from its passageway. When a slider is engaged upon its post and moved toward the associated passageway, the slider will wedge against and lock the post adjacent the point where it extends from the passageway. In an alternative embodiment, each slider has a slot adapted to engage a post in locked condition when the slider is pushed adjacent its passageway.
