Abstract

A motion picture reel is provided with releaseably engageable and disengageable components including a pair of identical, laterally confining retaining members and a hub located therebetween. The retaining members and the hub are all separable from each other. Each retaining member has a prong with a catch on it and a latching member with a latch defined on it located diametrically opposite the prong. The latching members each have radially outwardly diverging side walls. The latching members fit snugly into truncated sector-shaped cavities formed between radial spoke partitions between the central core and the rim of the hub. Stiffening webs extended transversely across the hub between some of the spoke partitions and have apertures in them that allow passage of the prongs through the stiffening webs and into engagement with the latching lips of the latching projections beyond. The tips of the prongs are accessible for release through the open bases of the latching members.
