A heating flange especially for the preheating of the intake air of an internal combustion engine with a frame ( 8 ), a supporting ceramic element ( 2 ) with a heating band ( 10 ) fitted thereto. The supporting ceramic element 2 is held in the frame at an inner side of the frame, and a support spring ( 1 ) is arranged between the supporting ceramic element ( 2 ) and the inner side of the frame. The support spring ( 1 ) is a leaf spring which is straight in the non-stressed state, and sits under an initial prestess between the supporting ceramic element ( 2 ) and the inner side of the frame. As a result of this configuration, low friction arises between the supporting ceramic element ( 2 ) and heating band ( 10 ), as well as leaf spring ( 1 ), which reduces failures due to vibratory loading, and a defined initial spring tension with a defined spring deflection is produced.
