Abstract

In a tube disconnecter (1), having a supply line (2) and a discharge line (3), having a closure element for disconnecting supply line and discharge line, and an aeration opening for aerating the discharge line, and also having a device (4, 4') for preventing backflow of the medium in the discharge line (3), a de-aeration opening (5) is arranged in the discharge line (3) between the supply opening (22) of the tube disconnecter (1) and the device (4, 4') for preventing backflow of the medium, in order to de-aerate the air which has penetrated into the discharge line during the disconnection process. <IMAGE>
