1. A ring binder for use in holding loose-leaf pages, the ring binder comprising:
an elongate body having a width, a length greater than the width and an axis extending along the length of the elongate body; rings for retaining loose-leaf pages, each ring including first and second ring members extending from and supported by the elongate body, the first and second ring members being moveable relative to one another between a closed position in which the first and second ring members together form a substantially continuous, closed loop for allowing loose leaf pages retained by the ring to be moved along the ring from one ring member to the other and an open position in which the first and second ring members form a discontinuous, open loop for adding or removing loose-leaf pages from the ring; and a retaining system operable to selectively and releasably hold the first and second ring members in the closed position, the retaining system comprising first and second interlocking formations adjacent ends of the first and second ring members, respectively, the first and second interlocking formations being selectively moveable relative to one another between a retaining position in which the retaining system holds the first and second ring members in the closed position and a non-retaining position in which the retaining system does not hold the first and second ring members in the closed position, wherein the interlocking formation of the first ring member includes at least one projection having a free end, the free end of the projection having at least one void and being adapted to be resiliently compressed by the interlocking formation of the second ring as the interlocking formations are moved from the non-retaining position to the retaining position, wherein the at least one projection extends from the first ring member to the free end in a direction along the axis of the elongate body. |
