Abstract
Abstract A suspension clip, particularly for the suspension filing of open-topped envelopes containing floppy discs for computers, comprises a hook member of U-shape having a transverse part from which extend two arms, one of which has on its outside a longitudinally extending groove, and a resiliently deflectable prong which is anchored at or adjacent said transverse part and extends along said groove. Thus, two clips can be used to suspend an envelope from two parallel rails of a suspension filing system. A suspension filing system which may be used with said clips comprises at least one rail for engagement by a clip, a retaining bar disposed above the level of and adjacent to and substantially parallel to said rail to prevent upwards dislodgment therefrom of a clip, and means mounting said bar so that it can be displaced to permit upwards removal of a clip from the rail.
