Abstract

The present invention relates to a heating flange, in particular for preheating air in an intake line leading to an internal combustion engine. The heating flange comprises at least one heating element for heating the air flowing past said heating element, and a body for mechanically holding and electrically contacting said heating element. For providing an improved heating flange, which is used in particular for preheating air in an intake line leading to an internal combustion engine and which guarantees fast heating of the intake air as well as increased robustness and simplified mounting, said body comprises a fastening bow having a substantially U-shaped cross-section, and said heating element comprises at least one substantially U-shaped meander loop which is fixedly connected to the base of said fastening bow.
