Abstract
A breathing tube system has a heating element, wherein a resistance wire extends several times to and fro in the longitudinal direction of a tube with wire terminals at one end and is held in the tube in parallel by means of a plurality of spreading elements located at spaced locations from one another in the longitudinal direction of the tube. The resistance wire extends at least four times in the longitudinal direction of the tube. The spreading elements have guide elements for receiving the resistance wire at the inner tube wall of the tube. The spreading elements with the resistance wire are displaceable in the tube in the longitudinal direction.
