Abstract: A structural connection between a tubular thermosetting plastics member and a thermoplastics end cap is described. An end of the tubular member is inserted into an annular, axially extending gap in the thermoplastics end cap. The inner and outer wall surfaces of the gap are threaded. Adhesive fills the space between the end of the tubular member and the threaded surfaces of the gap.

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.

Abstract: A clip is provided for use in the suspension filing of magazines, journals and like articles having sheets or pages held together in a spinal portion. The clip comprises a bifurcate part having two fingers engageable respectively inside and outside the spinal portion of a magazine to grip the spinal portion between them, and a hook part engageable over a side rail of a suspension filing system. By inserting a clip at each end of the spinal portion of a magazine and engaging the hooks over the two parallel rails of a suspension filing system, the magazine can be suspended with its spinal portion performing the function of the normal cross-bar in such a system.
