1. A flexible tube clip for a flexible tube having an interior which can be connected to a container and in said interior the pressure prevailing is different from that in its environment, comprising:

  • two arms between which the flexible tube is compressible to different extents so that the tube cross-section is closable, said tube having a longitudinal axis;

    the two arms being movable relative to one another transversely to the longitudinal axis of the flexible tube;

    a subsidiary chamber body having an interior space and having an outer wall, the interior space of which has a connection to the flexible tube;

    said outer wall being at least partly resilient so that the volume of the interior space is variable, with one variation of the volume the two arms are movable relative to one another and thus the flexible tube is compressible to different extents;

    the connection means between the interior space of the subsidiary chamber and the flexible tube comprising a subsidiary tube, or an opening in the flexible tube, which subsidiary tube or opening is disposed only outside said container;

    said subsidiary tube or said opening is connected, in relation to a clamp point, on the side of the flexible tube remote from the container which is to be connected;

    said arms being disposed on the wall of the subsidiary chamber in such a manner that through variation of the volume of the subsidiary chamber, the arms are movable relative to one another and the flexible tube can thereby be compressed to different extents;

    wherein the two arms move toward one another when the negative pressure in the flexible tube increases; and

    wherein the two arms move away from one another only when the negative pressure in the flexible tube is reduced.
