Document folder
 A document folder includes upper and lower sheets, and a C-shaped clamp. The upper and lower sheets has a common edge. The lower sheet has an opening formed adjacent to the common edge. The opening has opposed first and second edges which are parallel with the common edge. The lower sheet further has a plate member which has an edge fixedly connected to the internal face of the lower sheet in order to cover the opening. The C-shaped clamp has upper and lower clamping plates, and a curved portion. The lower clamping plate has a tapered projection which abuts the plate member. The C-shaped clamp is movable between a clamping position, where the curved portion of the C-shaped clamp abuts the common edge and a releasing position, where the shoulder portion of the projection abuts the first edge of the opening, preventing the C-shaped clamp from being separated from the upper and lower sheets.
