Claim:
A flexible corrugated hose fitting for flexible corrugated hoses having a corrugated pipe and a sheathing, the fitting comprising: a connecting element with an extension, which can be pushed into the corrugated tube, a clamping section adjoining the extension for receiving an exposed end of the corrugated pipe and a holding section, a fastening device provided on the extension for the axial securing of the corrugated pipe, having a clamping element, which can be pushed on the end of the corrugated pipe, and a pressing sleeve, which can be connected with the holding section of the connecting element, and which has a pipe-shaped section extending to the sheathing, wherein the extension is embodied in a pipe shape and has an essentially cylindrical outer surface, wherein the fastening device is a snap-in device, part of which are one or several snap-in protrusions, which are sawtooth-shaped in longitudinal section and are arranged on the exterior surface of the extension wherein, when several snap-in protrusions are provided, which are axially spaced apart from each other, the axial distance (x) between the snap-in protrusions matches the wave distance (x) of the corrugated pipe, or is a whole number multiple thereof, and wherein, the extension has at least one axial slit for making possible a radial movement of the areas of the extension supporting the snap-in protrusions.
