<p>Device for removably receiving a planar object, in particular a compact disk (CD), fitted with a central round receiving aperture. The device may be a plate comprising a recess to receive such planar object and a central clamp for the round receiving aperture of such planar object. The receiving plate comprises at least on one side, and in the vicinity of its edge, two mutually spaced boreholes for "threading" or stacking, for instance when using bar-shaped retainers or ring-binders. The boreholes each communicate through a slot of lesser width than the borehole diameters with the side edge of the receiving plate. Incisions are formed on and near both sides of the slots to form resilient wall portions bounding the slots.</p> |
