1. Electrical heating cable connecting device, in particular self-regulating heating cable (32, 132), at least one end part (33, 133) of the cable being introduced in an explosion-proof manner into a housing (1, 101) and at least one electrical lead being connected to one contact of an insulating member (19, 119), characterized in that the insulating member (19, 119) is releasably mounted closely surrounded in an unfilled inner chamber (20, 120) of an insulating casing (18, 118) resistant to the heating temperature, that the end part (33, 133) of the heating cable (32, 132) is clamped in a flame-proof manner in a passage of an elastomeric gasket (15, 115) resistant to the heating temperature, that the heating cable (32, 132) with the associated elastomeric gasket (15, 115) closes off the inner chamber (20, 120) of the insulating casing (18, 118) and is detachably fastened with a fire-proof gap (34, 134) on the periphery of the elastomeric gasket in an opening (35, 135) of the housing (1, 101) and that the housing (1, 101) is constructed as a pressure-resistant enclosure withstanding the pressure of an explosion of an explosive mixture in the inner chamber (20, 120) of the insulating casing (18, 118) at the heating temperature of the heating cable (32, 132) and preventing a transmission of the explosion to the atmosphere surrounding the housing (1, 101). |
