Double bent metal wires having a spring loaded configuration forming clasps, devices, apparatus, systems and methods for easily attaching and detaching hooks to fishing lures, feather hooks, jig heads, fishing lines, and the like. The clasp can have screw type threads for being threaded into an end of a fishing lure. The opposite end has a hook with a spring catch for closing the hook and allowing the clasp to attach to a loop end of a fishing hook. The spring catch is formed from two legs each having bent ends attached to a base of the hook by a crimp ring. To open the loop on the clasp, the spring catch can be pushed away from the hook opening, for attachment to loop ends of fishing hooks, and the like. The clasps can be used with attaching jewelry strands such as necklaces, bracelets, chains, and anklets together.
