Abstract
A locking ring binder assembly has a resilient sheet metal cover and a pair of operating levers rotatably mounted on the covers. A projection on the operating levers beneath the cover and a leg portion on the operating levers in alignment with the projection through a thickness of the cover locks the binder in a closed position even though the operating levers are not rotated to an over center position.
