Abstract: An explosion vent mounted to seal an opening formed on a wall of a closed space comprises a cover being dimensioned to fit on said opening and having a perimeter with an edge adapted to seal the cover against the opening with a sealing element. A spring element is arranged to hold the cover in the opening and the spring element has a direction of spring action. The cover is held by opposite retaining surfaces in the opening and the cover and he retaining surfaces are acting against the spring action of element. The sealing element is positioned against the opening so that the sealing force is directed at least partially crosswise to the direction of the spring action of the spring element.
