Abstract: A lock member is provided in a housing movably between a standby position and a connected position. In a state wherein the lock member is locked in the standby position, when a pipe is inserted into an opening portion of the housing, the lock member is unlocked so as to be movable into the connected position; however, a tip portion of a detection stopper abuts against a flange portion of the pipe so as to prevent the lock member from moving into the connected position. Next, when the pipe is inserted further, and the flange portion passes the position of the detection stopper, the detection stopper moves into the connected position together with the lock member.

Abstract: A connector for a fuel tank includes a cylindrical main body; a connecting cylinder body including an attachment portion of a pipe connecting the fuel tank and an external portion, and assembled with the cylindrical main body; and a reinforcing cylinder body housed inside the connecting cylinder body. By a stopper portion formed on an inside of the connecting cylinder body, and a holding end portion of the cylindrical main body positioned inside the connecting cylinder body by the above-mentioned assembling, the reinforcing cylinder body is sandwiched from both sides so that the reinforcing cylinder body is positioned on an inside of the attachment portion of the connecting cylinder body.
