Abstract
A high-pressure fluid line including a corrugated tube defining a fluid flow channel its interior, wherein a wall of the corrugated tube, in parallel with the extension direction of the fluid flow channel, comprises a sequence of wave peaks and wave troughs. The fluid line includes a braiding made of threads, which is applied to an outer periphery of the corrugated tube. The braiding bears tightly against the outer periphery of the corrugated tube at a substantially constant braiding angle over the entire corrugated tube. The braiding and the corrugated tube are connected at least at two mutually separate locations such that stretching of the corrugated tube in a longitudinal direction is accompanied by a reduction in a diameter of the braiding.
