Abstract
A medical tube-connector device that enables easy connection and disconnection without allowing channel ends to be touched by fingers. The first connector body includes a channel that can communicate with a tube, and is removably attached to the first connector body. The second connector body includes a channel and a concave part into which the protective cap can be inserted. A displaceable guide cap is attached to the second connector body. In a preparatory state, the concave part into which the protective cap can be inserted is open and the end of the channel is sealed. In the connected state, the end of the channel is open. The protective cap is maintained in the concave part so as to be detached from the first connector body and at the same time the channels of the first and second connector bodies communicate.
