Abstract

The present invention relates to a device for interrupting the operation of an apparatus in which a gaseous fluid is flowing. This device comprises a support 1 in a synthetic material exhibiting the shape of a rectangular plate with a leading edge 1a and trailing edge 1b to the gaseous fluid, a first upstream detector 5 sunk into the leading edge 1a, a second downstream detector 6 sunk into the trailing edge 1b, and a set of heating resistances 4 sunk into the support at a distance which is closer to the detector 5 than to the detector 6, while a metal plate 9 is fixed externally onto the faces of the support 1 in the region of the first detector 5. This device is intended especially to equip ducts in gas boilers.
