Apparatus used for holding a disc (12) including a lower surface and an upper surface with an opening extending between the surfaces, comprises a base (1) and a hub (2) extending upwards from the base. The hub includes a center portion (6) adapted to pass through the opening of the disc and engage the upper surface of the disc (12) to hold the disc on the hub. The hub (2) includes outer pieces (4), non-movable with respect to the base (1), for arresting downward movement of the disc (12) during its removal.

1. An apparatus for holding a disc that includes a lower surface and an upper surface with a central opening extending between the upper and lower surfaces; the apparatus comprising:a base; and a hub connected to the base and extending upwardly from the base; the hub including a central portion and outer portions that are diametrically opposed in relation to a center of the hub and separated from the central portion by respective slots; the central portion being connected at diametrically opposed ends to the base and having resilient portions allowing the central portion to be pushed from a resting position to a depressed position; the central portion including a pair of disc-engaging members for retaining a disc on the hub when the central portion is in its resting position and being movable towards one another when the central portion is moved from its resting position to its depressed position, thereby releasing the disc; and the diametrically opposed outer portions being non-movable with respect to the base for blocking movement of the disc toward the base when the central portion is moved from its resting position to its depressed position. 2. The apparatus of claim 1, wherein each outer portion includes an upwardly sloping outer wall and an abutment surface; the abutment surface upwardly offset from the base.3. The apparatus of claim 2, wherein the central portion includes a pair of upwardly sloping wall portions and a substantially horizontal second wall portion connected to each of the upwardly sloping wall portions; the substantially horizontal wall portion being disposed at the same height as the abutment surfaces of the outer portions.4. The apparatus of claim 3, wherein the second wall portion is substantially parallel to the base; the second wall portion having at least one continuous portion extending between the upward ends of the upwardly sloping first wall portions of the central portion.5. The apparatus of claim 1, wherein the central portion includes at least one section that extends continuously from one side of the hub to the other side of the hub.6. The apparatus of claim 5, wherein the central portion includes a gap between the disc-engaging members.7. The apparatus of claim 1, wherein the central portion has substantially parallel edges that extend across the hub in parallel relationship equidistant from the center of the hub.8. The apparatus of claim 1, wherein the disc-engaging members cooperate to form a central push button for the hub.9. The apparatus of claim 3, wherein the upwardly sloping outer walls of the outer portions and the upwardly sloping wall portions together form, in the absence of the slots in the resting position of the central portion, a frustoconical surface.10. The apparatus of claim 1, wherein the disc-engaging members include projections for extending over the top of the disc to retain the disc on the hub when the central portion is in its rest position.11. The apparatus of claim 10, wherein the projections are diametrically opposed in relation to the center of the hub.12. The apparatus of claim 3, wherein the disc-engaging members include a pair of arms extending upwardly from the substantially horizontal wall portion.13. The apparatus of claim 1, wherein the disc-engaging members include a pair of arms extending substantially perpendicular to the base.14. The apparatus of claim 13, wherein the arms include projections extending radially outwardly from the arms for extending over the top of the disc to retain the disc on the hub when the central portion is in its rest position.15. The apparatus of claim 14, wherein the arms cooperate to form a central push button for the hub.16. The apparatus of claim 13, wherein the arms are diametrically opposed in relation to the center of the hub.17. An apparatus for holding a disc having a lower surface and an upper surface with a central opening extending between the upper and lower surfaces; the apparatus comprising:a base defining an opening; and a hub connected to the base and covering a portion of the opening; the hub including a central portion that is connected to the base on opposite sides of the opening defined by the base and a pair of outer pieces disposed on opposites sides of the central portion; the outer pieces being adapted to support a disc and prevent the disc from moving downwardly with respect to the hub; the central portion including a pair of upwardly extending disc-engaging arms; the disc-engaging arms extending upwardly from the central portion; the disc-engaging arms being spaced from one another; the disc-engaging arms being adapted to be depressed from a resting position to a depressed position wherein the resting position holds a disc on the hub and the depressed position allows the disc to be removed from the hub; each outer piece including an upwardly sloping outer wall and an abutment surface; the abutment surface being substantially parallel to the base and disposed at the same height as the central portion; the central portion including a pair of upwardly sloping wall portions and a substantially horizontal second wall portion connected to each of the upwardly sloping wall portions; and the horizontal wall portion being disposed at the same height as the abutment surfaces of the outer pieces. 18. The apparatus of claim 17, wherein the second wall portion is substantially parallel to the base; the second wall portion having at least one continuous portion extending between the upward ends of the upwardly sloping first wall portions of the central portion.19. The apparatus of claim 18, wherein each of the arms extend substantially perpendicular to the horizontal wall portion of the central portion.
