A male connector is connectable to a female connector and includes: a flow path tubular member that has an opening at one end portion in an extending direction； a valve body that closes the opening of the flow path tubular member； a housing main body； and a moving body that moves with respect to the housing main body and deforms the valve body or the like so as to change a mode between a first mode in which the opening is closed by the valve body and a second mode in which the opening is open from the valve body. The moving body includes a locking portion that locks the female connector in a state in which the valve body and an elastic valve body of the female connector abut on each other. Any one of the housing main body and the moving body includes a switching portion that is displaceable between a restriction position to restrict movement of the other of the housing main body and the moving body so as to maintain the first mode and an allowing position to allow the movement of the other so as to change from the first mode to the second mode while maintaining a state in which the locking portion locks the female connector.
