A binding device for files and binders in which rings to be inserted into binding holes of an object to be bound are openably and closeably secured to a base plate so as to be opened and closed by an opening-closing mechanism including a rotationally movable lever. In the binding device, a first ring member and a second ring member are configured such that they are interlocked with the opening-closing mechanism including the lever so as to be opened and closed about respective pivot portions and provided in the lower end thereof by rotationally moving the lever. In addition, the first ring member and the second ring member are secured in an opened state when opened, and the lever is secured such that the first ring member and the second ring member are maintained in the opened state.
