An adjustable document file binding device includes a binding seat and at least one binding element, wherein the binding element is slidably mounted in the binding seat to form a space for holding files by fasteners. The binding seat is a rectangular frame constituted by a bottom wall, a rear wall perpendicular to the bottom wall and two side walls at edges of the bottom wall and the rear wall, which opens in two directions. The binding element is a U-shape body corresponding to the binding seat. One or plurals of retractable and detachable connectors are mounted between the binding seat and the binding elements for binding loose leaves. When two binding elements are used, the binding device forms at least two spaces for receiving files. Therefore, the device is adapted to bind loose leaves and other files concurrently.
