Claim:
An optical connector that is attached to an optical cable in which an optical fiber is covered with a cable sheath, the optical connector comprising: a ferrule that holds a distal end portion of the optical fiber exposed from the cable sheath; and a one piece molded housing having in one end portion thereof a first concave portion for the ferrule, which serves to accommodate the ferrule, wherein the ferrule has a body portion and a collar portion formed at one end side of the body portion and is introduced into the first concave portion for the ferrule from the collar portion side, a hook portion for the ferrule, which is made of an elastically deformable material, is provided in a protruding condition at an inner wall surface extending between an opening and a bottom surface of the first concave portion for the ferrule in the housing, and the hook portion for the ferrule is elastically deformed and guides the collar portion toward the bottom surface of the first concave portion for the ferrule when the ferrule is introduced into the first concave portion for the ferrule, and is elastically restored and locks the collar portion when the collar portion reaches a space between the hook portion for the ferrule and the bottom surface of the first concave portion for the ferrule, the housing includes a second concave portion for an elastic member, which is open at the bottom surface of the first concave portion for the ferrule and accommodates the elastic member, and the elastic member accommodated in the second concave portion for the elastic member biases the collar portion of the ferrule accommodated between the hook portion for the ferrule and the bottom surface of the first concave portion for the ferrule toward the hook portion for the ferrule, and a bottom surface of the second concave portion against which the elastic member is pushed is formed in the one piece molded housing.
