ABSTRACT:
An arrangement for connecting two parts of a fluid system, preferably an aseptic system, by which the pressure gradient acts from the outside to the inside. The one system part carries an O-ring in a groove open to the other system part and open radially outwardly and the other system part is pressed against the O-ring by an axial holding device. To avoid dead space, in which bacteria could deposit, a space formed by the O-ring, the two system parts and the axial holding device is provided with a communication to the surroundings.
