  • Patent number: 5915946
    Abstract: The present invention discloses a split ring for fishing having two ring portions arranged vertically and made by bending a hard wire having appropriate elasticity into the form of a figure eight, wherein both ends of the wire are overlapped with each other in close or almost close contact with each other so as to form a part of one of the ring portions. With the above-mentioned structure, the lure and the hook are not entangled with each other. In addition, the lure and the hook can have larger freedom of movement, and this is likely to bring a bigger fish catch. Furthermore, the hook can be attached to and removed from the lure easily, and the lure can be connected to and removed from the fishing line easily.
