Abstract

The present invention relates to a plug (1) comprising at least two discrete glass discs (2), wherein there is provided between the glass discs a liquid (3) which contributes to load uptake and load distribution, and a pin-/claw device (4) is arranged to be pressed in a radial direction into at least one of the glass discs (2). A distinctive feature of the plug is that it does not include a functional drainage system, and the pin-/claw device (4) is arranged such that on activation there occurs a pressure leakage through the glass disc (2). Also suggested according to the invention is a volume compensator/constant pressure regulator (20, 21, 22; 23; 24).
