A reinforced hose coupling includes an end fitting having first and second, axially extending sections with the first section comprising a connector and a secon d section providing a nipple with external grooves. A metal ferrule is mounted on the nipple and is connected to the end fitting. The ferrule has an external depression formed in a side thereof. Two holes are formed in this depression and extend through the wall of the ferrule. A reinforced hose end having flexible tubular rubber or plastic layers is crimped between the ferrule and the nipple. The hose end has an outer wire extending about the exterior of the tubular layers. An end piece of this wire extends through th e holes and across the depression helping to secure the hose end to the coupling and providing an indication to the user that the coupling is in usable condition. Preferably the ferrule is formed with a circumferentially extending internal rim at one end, which rim is forced into a circumferential groove formed in the end-fitting.
