Abstract
A ring binder has an elongate body and rings including ring members moveable between closed position and open positions. A retaining system selectively and releasably holds the ring members of at least one ring in the closed position. The retaining system includes interlocking formations adjacent ends of the ring members that are moveable between retaining and non-retaining positions. The first interlocking formation includes a recessed region and a projection extending upwardly. The second interlocking formation includes a vaulted region and a projection extending downwardly. The first projection is received in the vaulted region and the second projection is received in the recessed region when the interlocking formations are in the retaining position. The interlocking formations are configured so that movement of the interlocking formations relative to one another in the direction of a longitudinal axis of the body is blocked when the interlocking formations are in the retaining position.
