A motion picture reel is comprised of separable components including a hub formed with a hollow central, cylindrical sleeve and a pair of side retainers on opposing sides of the hub that hold the film therebetween. Each of the side retainers is provided with a central core located on its inner surface. Each core has a generally cylindrical configuration. A prong is formed to project longitudinally from each core parallel to and at a spaced distance from the axis of rotation. A corresponding prong receiving socket is defined in the core diametrically opposite the prong. The cores of the side retainers are inserted into the central, tubular sleeve of the hub so that the prong of each core enters the prong receiving socket or cavity of the other core. A slight counterrotation of the side retainers relative to each other latches the hooks on the ends of the prongs into the sockets. Releaseable hub latching fingers on each of the retainers engage the side retainers with the hub as the hooks of the prongs are engaged in the sockets.
