Heating flange, in particular for air preheating in an intake manifold of an internal combustion engine

The heated flange has at least one heating element (102,104) for heating the passing air and a base body (101) for mechanically holding and electrically contacting the heating element. The base body has a retaining device (106) with an essentially U-shaped cross-section and the heating element contains at least one essentially U-shaped meandering loop fixed to the retaining device at its base.
