Abstract: A male connector is connectable to a female connector that includes an elastic valve body, and includes: a housing, a flow passage tubular member having an opening formed thereon, and a valve body. The housing includes a housing body, and a movable body that deforms or moves the valve body so as to change a configuration between a first configuration in which the opening of the flow passage tubular member is closed by the valve body, and a second configuration in which the opening of the flow passage tubular member is exposed from the valve body. The movable body includes a first locking portion configured to lock the female connector in the first configuration, and the housing body includes a second locking portion configured to lock the female connector in the second configuration.

Abstract: A female connector that allows connection of a male connector including a lock claw and a channel connection. The female connector includes a cap including a top provided with an opening and a peripheral wall extending from an outer peripheral edge of the top; a housing including a cylindrical wall and an engaging protrusion protruding from an outer peripheral surface of the cylindrical wall to form a lower surface engaged with the lock claw; and a valve including a portion sandwiched between the top and the cylindrical wall and a portion penetrating the valve in up-and-down direction. A boundary is formed between an upper surface of the engaging protrusion and a lower end face of the peripheral wall. The lower end face is smaller than the upper surface in outer diameter. The engaging protrusion has an outer peripheral surface including a portion with a diameter increasing downward from the boundary.
