Abstract
The invention relates to an explosion-proof arrangement () with an explosion-proof housing () which has a wall opening () in a housing wall (). The wall thickness (d) of the housing wall () is so small that it is not possible to form a thread there in order to screw in a connecting body () for a line to pass through or for receiving an assembly so as to ensure protection against flame transmission. According to the invention, a connecting body (), which has a flange () with a flange face (), is inserted into the wall opening (). The flange face () delimits a flameproof gap () by way of the housing wall (). The dimensions of a gap or intermediate space between the connecting body () and a boundary face () of the housing wall (), which boundary face delimits the wall opening (), are not important. The protection against flame transmission can be provided solely by the flameproof gap () between the flange face () and the housing wall ().
