A ring binder mechanism for retaining loose-leaf pages comprises a housing supporting two hinge plates for pivoting motion to open and close ring members. Paired ring members of the mechanism attach to the hinge plates and move therewith between the open and closed positions. Free ends of the paired ring members each have a interlocking formation that is capable of securely joining together when the ring members are in the closed position. The interlocking formations hold the ring members against misalignment in all directions transverse to longitudinal centerlines of the ring members when the ring members are in the closed position. Some formations are additionally capable of positively engaging each other as the ring members come together to actively bias the ring members into accurate alignment.
