Beschreibung
Zusammenfassung:	A hose coupling for high-pressure hoses includes a stem and a ridged outer ferrule connected to the stem, wherein a staggered portion is disposed on the stem in the proximity of the connection of the stem and the ridged outer ferrule, where the diameter of the staggered portion is larger than the diameter of the stem, and the staggered portion has an undercut and a cutting edge. Also, a high-pressure hose fitted with the above swaged coupling, and a method for producing it. In the method, prior to swaging, the cover of the hose is removed at the portion where the cover is in connection with the ridges of the ridged outer ferrule of the hose coupling, and the hose liner and an optionally included load distribution textile ply or cord fabric ply are also removed from the hose end before swaging at a length not longer than the length of the staggered portion of the stem.
