ABSTRACT:
One end (4a) of a supply tube (4) opening out into the three-way connector is closed by a diaphragm (9) and filled with fresh fluid. This end is situated opposite one end of a duct (3b;36) to which a connection tube (3) is connected, with which it is axially aligned. This duct end has a pointed tip (8; 37) of hard plastic material. The end of the supply tube is axially displaceable in a chamber (2) of the three-way connector. By moving this end toward the tip of the duct end, the diaphragm is pierced by the tip, so that the fresh fluid can flow from the supply tube into the connection tube. One end of a drain tube (5) runs perpendicular to the duct end and opens out in the chamber. This closed three-way connector cannot be contaminated, is easy to use, and is largely proof against incorrect manipulation.
