An overheating destructive conductive plate safety clip as well as a plug and a socket using that conductive plate safety clip are disclosed. The overheating destructive conductive plate safety clip limits two conductive plates from contacting with each other to form a closed path, and is destructed when overheating, opening the two conductive plates by an elastic force to form an open circuit. The overheating destructive conductive plate safety clip includes a first limiting element, a second limiting element and a connecting element. At least one of the first limiting element, the second limiting element and the connecting element is made of plastic, at least one of the first limiting element and the second limiting element is made of metal, and a destruction part is formed at a place where the plastic material is connected with the metallic material.
