The male connector () includes a connector body () and a lock nut (). The connector body () includes a male luer (), first female threading () that surrounds the male luer (), a base end portion () that is inserted into a tube (), a fixed protrusion () formed on the base end portion (), and a spiral protrusion () between the male luer () and the base end portion (). The lock nut () includes second female threading () that is screwed together with the spiral protrusion (). When the spiral protrusion () and the second female threading () are screwed together, the base end portion () and the lock nut () clamp the tube ().
