Abstract
An improved ring binder (28) comprises a frame (F') having a pair of leafs (L1', L2') extending lengthwise of the frame. Binder rings (R) are each formed of two binder ring halves (R1, R2) one end (E) of each of which is attached to one of the leafs. Boosters (10) are attached to each end of the frame, and the leafs each include a notch (24, 26) formed at their respective ends. Each booster includes a tang (12) captured in the notch. A cover or shield (40) fits over the frame and extends beyond the location of the boosters. The sides of the cover are now crimped about the boosters to secure them in place.
