A medical instrument, comprising a female connector member incorporating a female taper portion capable of being joined to a medical instrument member having a male connector member incorporating a male taper portion and a ring member provided to said male connector member so as to encircle said male taper portion and having at least one threaded ridge formed on the inner circumferential surface thereof, which medical instrument is characterized by having formed on the outer periphery of said female connector member at least one threaded groove capable of being helically fitted on said threaded ridge of said ring member and having formed at a desired position in said threaded groove a rib adapted to engage with said threaded ridge when said threaded groove is being helically fitted on said threaded ridge. The first medical instrument member is, for example, a three-way faucet, and the second medical instrument member is, for example, an artificial organ such as a Ruer port connector and an artificial lung, catheters, blood circuits for the artificial organs.
