    摘要: A motion picture film reel is comprised of a pair of identical retaining members each formed with a flat, side cheek-plate member having a central axis of rotation and a hub-engaging region. An axially extending portion projects from each central, hub-engaging region in generally perpendicular alignment therewith. Each axially extending portion includes a base with a pair of diametrically opposed channels extending lengthwise along the base and a pair of resilient, diametrically opposed prongs. The prongs both have radially outwardly directed catches thereon. The prongs are inserted through a central, axial opening in a disk-shaped hub from the opposite sides thereof. The opposite edges of the core on the opposite sides of the hub form latching ledges so that the catches on the prongs releasably engage the latching ledges on the two opposite sides of the hub. The retaining members are thereby held releasably engaged to the central hub located therebetween. One or both retaining members can be removed simply by pressing the catches at the ends of the prongs together and pulling the retaining members apart from each other.
