A ring binder mechanism includes a housing, a ring support, and rings for holding loose-leaf pages. Each ring includes a first ring member and a second ring member that are moveable between a closed position and an opened position. An actuator is mounted on the housing for moving the ring members from the closed position to the opened position. A travel bar has at least one locking element and is moveable between a locked position wherein the ring members are locked in the closed position and an unlocked position wherein the ring members are capable of being moved to the opened position. An intermediate connector operably connects the travel bar to the actuator. A portion of the intermediate connector is captured by and moveable with a wide section of a mounting groove in the travel bar so the intermediate connector can move relative to the travel bar.
