Claims.—(1.) In a binder, the combination of a strip provided with a pair of fixed posts, a clamping-strip, a pair of grippers separate and distinct from each other fixed so as to be bodily immovable on said clamping-strip, each gripper consisting of two spring jaws arranged to move to and from each other in the same plane and adapted to engage the exterior surface of one of said posts, and means carried by the clamping-strip independent of the posts for causing the gripper-jaws to move to and from each other whereby the posts may be engaged or disengaged by said grippers.
