Abstract
A safety element is disclosed for influencing or inspecting fluid media in a duct, in particular a double-walled safety duct whose walls are separated by a hollow space. The safety element has a housing formed by walls and flanges for sealingly connecting it to the duct. The housing is surrounded on all sides by a second wall (6) separated from the first wall (5) by a hollow space (7) which is closed in a gas-tight manner and can be connected with measurement equipment for inspecting its contents. The hollow space (7) communicates through one or several bores (13) with a groove (15) shaped around the duct into the sealing surface (14) of the flange (1) or its seal (18).

A safety function element for influencing or controlling fluid medium in a line, comprising:
- a housing formed by a first wall with said housing being enclosed on all sides by a second wall, said second wall being at a spaced-distance from said first wall with a hollow space existing between said first wall and said second wall, the hollow space being closed so as to be airtight, said housing having one or more flanges for connecting said housing to the line;
- a leak detection device for detecting leakage into the hollow space, the hollow space being connected via one or more bores to a groove disposed circumferentially to the line in a sealing surface.
