According to the invention, at least one of the longitudinal walls comprises a displacement reducing element (10) protruding from the wall. The displacement reducing element (10) comprises a ramp (11) which is gradually inclined into the housing towards the opposite longitudinal wall, said displacement reducing element (10) being arranged such that its downstream end (14, 15) extends at a distance from the rear wall (21).)

1. Frame (3) for an electric heating device (1), the electric heating device (1) being intended for heating an air flow circulating inside a ventilation, heating and/or air-conditioning apparatus of a motor vehicle, the frame (3) comprising at least one housing (7) intended to accommodate at least one heating element (5), the housing (7) being delimited by a plurality of longitudinal walls (23, 25) forming a longitudinal insertion path for the heating element, the insertion path being delimited longitudinally by end walls (21) extending from opposite sides of an opening (50) through which a heating element (5) intended to be located in the housing can be inserted, the direction of insertion being delimited from the opening (50) to the end walls (21),

characterized in that at least one of the longitudinal walls (23, 25) of the housing (7) comprises a displacement reducing element (10) projecting from said wall, said displacement reducing element (10) having a slope (11) extending towards the opposite longitudinal wall progressively towards the interior of the housing with respect to the insertion direction, said displacement reducing element (10) being arranged so that its downstream end (14, 15) extends at a distance from said end wall (21).

2. The frame according to claim 1, characterized in that said longitudinal walls (23, 25) comprise a plurality of displacement reducing elements (10).

3. The frame according to any one of the preceding claims, characterized in that the longitudinal walls (23, 25) defining the casing (7) each comprise at least one displacement reducing element (10).

4. The frame according to any one of the preceding claims, characterized in that the displacement reducing element (10) has an inclined surface (11) forming a slope, the inclined surface (11) having an inclination angle (a) with respect to the longitudinal wall (23, 25) in which the displacement reducing element (10) is located.

5. The frame according to any of the preceding claims, characterized in that the displacement reduction element (10) has at least one ridge (13, 17) arranged in a continuation of the ramp (11) and forming the apex of the displacement reduction element, which ridge is the innermost part of the displacement reduction element in the housing.

6. The frame according to any one of the preceding claims, characterized in that the downstream end of the displacement reducing element (10) has a downstream face (14) substantially parallel to the end wall (21).

7. The frame according to any one of the preceding claims, characterized in that the displacement reducing element (10) is, with respect to its longitudinal dimension, in the region defined between the end wall (21) and a central portion of the casing (7).

8. The frame according to any one of the preceding claims, characterized in that the displacement reducing element (10) is integral with the longitudinal wall (23, 25) in which the displacement reducing element (10) is located.

9. The frame according to any one of the preceding claims, characterized in that the inclined surface (11) has a horizontal portion (16) parallel to the longitudinal walls (23, 25) in which the displacement reducing elements (10) are located.

10. An electric heating device (1) comprising at least one heating element (5), characterized in that it comprises a frame (3) according to any one of the preceding claims, in which said at least one heating element (5) is arranged.
