Abstract: A connector having a contact made of metal, and comprises a pair of elastic arms adapted to clamp a conductor of a wire, so as to electrically contact the conductor. A first release structure is on one of the pair of elastic arms and a second release structure, facing the first release structure, is on the other of the pair of elastic arms.
