A binding element adapted for binding an apertured stack of sheets into a book. The binding element comprises a first binding strip from which project a plurality of spaced studs adapted to be positioned through the apertures; and a second binding strip having a plurality of openings sized to freely receive the studs to afford positioning the second strip over ends of the studs projecting beyond the stack of sheets. Blocks on the second strip can then be pressed into the openings to forcefully engage the studs extending through the openings with teeth along the walls of the openings so that the teeth will indent the studs and maintain the position of the studs in the second strip. The ends of the studs projecting beyond the second strip can then be removed.
