The device has a disk-shaped housing plate (2) sealed by O-rings (3, 4) against a cover plate (5), where the O-rings are concentrically arranged. A space limited by the O-ring (3) is connected with a pressurized component e.g. pipeline (1) such as bag line, to be secured, and another space lying between the O-rings is connected with a low pressure source. The component to be secured is arranged in the center of the housing plate or outside of the center of the housing plate. A vacuum is introduced over a vacuum connection (6). |
