Abstract: A device for the quick connection and disconnection of a fish hook to the end of a fishing line includes a sister hook arrangement. The device is extraordinarily strong for its size and weight providing a significant advantage over known arrangements. The sister hook arrangement can be connected directly to a swivel which in turn is tied directly to the end of the fishing line or can be part of a fishing leader which would also include a swivel. The sister hook arrangement includes mirror image sister elements pivotally attached to one another such they can be spread to an open position for the engagement of an attachment loop of a fish hook thereon and pivoted to a closed position to fixedly secure the fish hook relative thereto.
