PROBLEM TO BE SOLVED: To provide a safe and easy-to-use releasable link for releasing a fishing tackle from a fishing line while keeping the fishing tool of the tackle in a locked state by reacting with a prescribed pulling action of the fishing line and resistant to the accidental release in the case that the fishing tool connected to a tackle is entangled and locked in seawater with a hazard such as sea grass, gap between stones, cavity of a rock, palisade, etc. SOLUTION: The linking device is a spiral releasing link member 1 obtained by closely winding an elastic metal wire several turns. A pair of the releasing linking devices 1 are linearly placed in parallel, a hooking part Aa of a fishing tool A is connected to a releasing link member 1, placing the other releasing link member 1 at the side of the rotating ring Ba of a swivel B or a fishing line C, and the accidental locked state of the fishing tool A occurring in fishing with a hazard can be released by applying a prescribed pulling force to the fishing line C to release the tension in the locked state.
