Abstract
A heatable hose (), in particular a respiration hose, having a flexible hose wall (), shall guarantee through its design that a contact of the electric conductors or heating wires () accommodated in the hose () and, thus, a short circuit, is excluded. For this purpose, the hose () is equipped with a plurality of reinforcing ribs (), each of which winds around the hose wall () in the manner of a helical line and which form together a multiple-threaded helical line, at least two reinforcing ribs () being provided, each of which encloses a heating wire () designed for heating the hose. Each heating wire () is preferably a single-conductor wire.
