Abstract
Filing unit for the storage of recording tape cassettes in which one or more loose leaf pages or sheets are insertable in a loose leaf ring binder. Each sheet has a plurality of retainer clips affixed thereto. The clips are formed from a strip of resilient material with a base portion and upwardly extending post portions spaced apart a distance approximately equal to the reel spacing of the cassettes to be held thereby. Each post extends generally perpendicularly from the base and includes an upwardly opening slot defining two spring finger portions, each having an outwardly extending lug at its upper edge to snugly engage the wall within the reel opening of the cassette.
