ABSTRACT:
The invention relates to a fastener for the resilent fillets or strips which are used to hold fast various kinds of papers in a folder or file. The fastener (10) has the shape of a bar (12) of plastics or sheet metal, at each end provided with a first notch (14) in one side of the bar and, closer to the end of the bar, a second notch (18) narrower than the first notch (14) and extending from the opposite side of the bar to form a cantilevered end portion or first tongue (15) substantially perpendicular to the longitudinal direction of the bar, whereas a longitudinal groove (22) extends from the inner end of said second notch (18) in a direction away from the end of the bar, to form a second cantilevered tongue (25). The strips (20) are inserted into the first notches (14), bent down and clamped between the tongues (15 and 25) at the ends of the bar (12) by being pushed underneath the first tongues (15) and above the second tongues (25). The invention also relates to a folder which cooperates with the fastener (10) and has strips punched from the material of the folder itself for securing the papers.
