1. An electrical heating element for an electrical heating device, the electrical heating element comprising:
a coiled resistive wire with a flat ribbon geometry and a connector assembly, wherein the resistive wire is coiled into coils with an inner diameter, an outer diameter, and a distance between adjacent coils wherein a flat side of the resistive wire runs parallel to a coil axis of the resistive wire, and wherein the connector assembly has at least one connection element that is in surface contact in one section of the resistive wire, a largest outer diameter of the connecting assembly being equal to the outer diameter of the coiled resistive wire.
