The invention discloses a quick locking connecting fishhook which comprises a fishhook body, a fishhook elastic sheet and a fishhook clamp. The fishhook elastic sheet is assembled on the inner side of the fishhook body. The fishhook body and the fishhook elastic sheet are clamped by the fishhook clamp, so that the fishhook elastic sheet moves elastically so as to lock or unlock a lock hole, and the fishhook and an object are rapidly connected, locked and rapidly unlocked. Compared with a traditional rope tying mode, 70% to 90% of time can be saved, and the fishhook is quite convenient and quick to use; in addition, due to the fact that the fishhook elastic sheet is provided with three elastic deformation bends which serve as multiple springs, the coefficient of resilience of the fishhook elastic sheet can be effectively increased, elastic force can not be lost after multiple times of pressing, and the service life of a product is effectively prolonged. By the adoption of the fishhook elastic sheet, an opening of a chamfer can be tightly sealed through a locking part of the fishhook elastic sheet, so that when hung on the object, the quick locking connecting fishhook is not easily disengaged from the object and is reliable in use.
