The invention relates to a frame () for an electric heating device (), comprising at least one housing () intended to receive a heating element (), said housing being defined by a plurality of longitudinal walls () forming an insertion path for a heating element, and said insertion path being defined longitudinally by a back wall extending opposite an opening through which the heating element can be inserted into the housing. According to the invention, at least one of the longitudinal walls comprises a displacement reducing element () projecting from the wall. The displacement reducing element () comprises a ramp () that slopes gradually into the housing, towards the opposite longitudinal wall, said displacement reducing element () being arranged such that the downstream end () thereof extends at a distance from the back wall ().
