FIELD: machine building.
SUBSTANCE: group of inventions refers to a hose coupling and method of its production. A hose coupling comprises a pin with a groove of the first width directed radially inside and including the lower surface from which the first and the second inclined surfaces pass radially outside to the outer surface of the pin. The coupling fixed to the pin comprises an engaging wedge of the second width directed radially inside before pressing on the pin; and the second width exceeds the first one.
