<p>An improved rosette for securing at least one disc shaped element having a central aperture includes a raised circular hub having a substantially cylindrical side wall, the hub (14) projecting upward from a planar base (2); at least one resilient, arcuate, circumferentially extending finger (6) integrally formed with the hub and extending along the perimeter of the hub, each finger being formed integrally with the hub at one end and free at the other end; at least one aperture (12) defined in the base, the number of apertures corresponding to the number of fingers, the fingers being arranged so that the free ends (6a) thereof overhang the apertures for permitting the free ends to substantially unobstructedly deflect arcuately inwardly when the disc is inserted on the hub; and a radially extending protrusion on the free end of each finger projecting outwardly beyond the outside diameter of the hub.</p> |
