(54) Locking follower for ring binder


(57) A paper retainer 20 is detachably attached to a binder 17 provided with binding legs 16 erecting from an upper surface of a base 15. The paper retainer 20 includes a bar-like body portion 30. At both lengthwise ends of the body portion 30, there are formed first opening areas 33, 33 extending obliquely and allowing insertion of the binding legs 16, 16 therethrough, and second opening areas 34, 34 formed continuously to the first opening areas and being able to clamp the binding legs 16, 16 in the radial direction. By pressing an operating tab portion 31 included in the body portion 30 with the binding legs 16, 16 inserted respectively through the first opening areas 33, 33, the body portion 30 is rotated to forcibly position the binding legs 16, 16 into the second opening areas 34, 34, thereby fixedly holding the paper retainer 20 in place.
