ABSTRACT OF THE DISCLOSURE A hose coupling for permanent attachment to a hose having a reinforcing braid layer intermediate inner and outer layers of rubber or plastic has an outer sleeve which is crimped to the hose at at least three axially spaced zones. The coupling includes an insert inside the hose having axially spaced annular ridges engag- ing the inner surface of the hose, The outermost crimped zone overlies a ridge and the spacing between the crimped zones is greater than the spacing between the annular ridges to provide spaced inwardly progressive zones of progressively less crimping pressure.
