A plug for a connector includes an insertion portion, and the insertion portion includes an O-ring abutment portion and a creep prevention portion. Also, when the insertion portion of the plug for a connector is inserted in a mouth portion of a connector, the O-ring abutting portion abuts against an O-ring mounted inside the connector, and closes the mouth portion of the connector. Also, the creep prevention portion prevents a creep of a lock member which is in a standby position.
