ABSTRACT:
In a folder for receiving documentary material, which is provided with profile bars (3) and slides (6) guided on these for retaining thread-on wires (5) insertable through orifices in the profile bar (3), a cam (9) located on the profile bar is used to retain the slide (6) in a filing position, and this cam is formed by a profile-bar bottom section punched out of the profile bar (3) and extending obliquely upwards towards the end of the profile bar and makes it possible to retain especially securely an engagement stop (17) which is located on the slide (6) and which, if required, can be lifted by the user over the cam (9) in order to displace the slide (6) towards the center of the profile bar (3).
