Classification: CPC H | IPC H

Claim 0:
1. An electrical tubular heating element for providing electric heat, the electrical tubular heating element comprising:
a tubular metal sheath having an interior; and
an electrical heating element positioned within the interior, the electrical heating element constructed of a linear solid elongate resistive wire that extends concentric to a tube axis of the tubular metal sheath, the electrical heating element arranged electrically insulated at least in sections from the tubular metal sheath, the electrical heating element having a base body, the base body comprised of one or more sections of the electrical heating element, each of the one or more sections of the electrical heating element having an essentially constant cross section and two end sections including a first end section and a second end section, the first end section being subjected to a shape-changing machining process so that a cross section of the first end section at least in sub-areas of the first end section is reduced in comparison to the essentially constant cross section of the base body.
