The electric heating arrangement (1) has a tubular housing (2) in which is provided at least one PTC heating element (20) and at least one pair of metallic heat dissipators (9) between which the at least one heating element (20) is clamped and which for this purpose each comprise a base portion (10) facing the at least one heating element and one or two curved legs (15) projecting from said base portion, which adapt themselves resiliently to the inner surface of the surrounding wall of the housing (2). The invention provides that the legs (15) taper toward their free ends and/or that the base portion (10) is thicker than the legs (15) projecting it.
