Loose leaf retainer for file folders










Image Number 3 for United States Patent #4932804.

A pair of flexible retainer strips each of which can be held in ring configuration by a head and socket at opposite ends of the strip which interlock to retain a stack of perforated sheets in a file folder. Each retainer strip is slidably mounted in a separate guide channel formed in an anchor element securable to the cover of a file folder. The ends of the strip can be readily uncoupled to enable the insertion in or removal of a sheet at any location in the stack without having to remove any of the remaining sheets of the stack from the retainer strip.
