Abstract

A sealed housing of an electric heating device to be installed in a motor vehicle includes a housing lower part and a housing cover abutting on the housing lower part via an intermediate sealing element. An elongate positive locking element, which interconnects the housing lower part and the housing cover in a form fit manner, is provided between opposed contact surfaces of the housing lower part and a housing cover. The positive locking element abuts on the contact surfaces under a pretensioning force caused by compression of the sealing element. A method of producing a sealed housing also is disclosed via which the contact surfaces move into contact with the elongate positive locking element under a pretensioning force of the sealing element.
