Abstract (en)
[origin: US4678357A] A device for binding holed sheets or a ring book fastener includes a binding cover elastically supported by supporting elements and receiving a plurality of rings spaced from each other along the axis of the binding cover and connected thereto. Each ring is comprised of two ring halves which are releasably engageable with each other. Each ring half is provided at the end thereof cooperating with the end of the other ring half with a tooth-shaped projection engageable in a tooth gap-shaped recess of the other ring half so as to produce a lock preventing a displacement of the ring halves in the closed position in the direction transverse to the closing direction.
