ABSTRACT:
A binder comprises suspension bars, each defining a channel with apertures leading into the channel adjacent the ends thereof. Flexible support elements are threaded through holes in sheets of paper to be received in the binder so that the paper is carried upon the elements. The channel in each suspension bar is formed and dimensioned so as to releasably retain the ends of each element therein without the need for separate retaining means. The binder is assembled by passing the ends of the elements through the apertures and pushing them into the channel where they are held in place.
