Beschreibung
Zusammenfassung:	An electric heating device has several PTC heating elements that are arranged in a circulation chamber. The electric heating device includes a heating element casing which fits as a structural unit at least one PTC element and contact plates that energize said PTC element and form contact strips for an electrical plug connection. A partition wall separates the circulation chamber from a connection chamber in which the contact strips of the PTC heating element penetrating the partition wall are exposed and are electrically connected. A plug connection is formed between the partition wall and the PTC heating element and via which the PTC heating element is held in a frictionally engaged and/or in positive fit manner on the partition wall in the direction of insertion.
