Patent ID: 8096588

Claim:
A hose coupling comprising: a main hollow body formed of plastic material having a first end, a second end, a first hollow cylindrical section extending axially from the second end toward the first end and terminating in a radially inwardly projecting shoulder, and a second hollow cylindrical section extending from the first end toward the second end and terminating at the shoulder, the first hollow cylindrical section having a substantially uniform bore; a hollow expandable sleeve having a first end and a second end and disposed coaxially within the first hollow cylindrical section of the main body, wherein the first end of the expandable sleeve is outwardly flared into the second hollow cylindrical section and abuts the inwardly projecting shoulder of the main body to limit a motion of the sleeve relative to the main body, and wherein an outer surface of the sleeve is spaced from an inner surface of the first hollow cylindrical section of the main body defining a cylindrical zone therebetween of a first thickness; and a hollow flexible and resilient hose having a wall of a thickness greater than the first thickness of the cylindrical zone between the outer surface of the expandable sleeve and the inner surface of the first hollow cylindrical section of the main body, wherein the hose is disposed in the cylindrical zone and an end of the hose is abutting the shoulder of the main body, and wherein the hollow expandable sleeve is expanded radially outwardly to secure the hose.
