Abstract
A ring type binder for perforated sheets or the like in which two members are coaxially secured so that a slot is formed along each longitudinal edge of the members. Another partially open ring member is provided that is configured to be slidably received in the slots so that ring member may be moved from an opened to a closed position. A locking device is provided so that the binder may be selectively locked in the closed portion, thereby preventing the unwanted shifting of the members.
