A fluid pressure hose coupling for connecting a flexible hose to a pressurized fluid line is described. The coupling has a connecting end section for securement to a pressurizable line and a cylindrical nipple end section for securing an end section of a flexible hose thereto. The nipple end section has a tapered cone-like outer surface having a larger outer diameter section at a free end thereof. A cylindrical hose clamping sleeve is positionable about the nipple end section and also has an inwardly tapered inner surface whose diameter is larger at the front end thereof and wherein the inner surface of the clamping sleeve and the outer surface of the cylindrical nipple end section extend parallel to one another. By positioning a flexible hose end section over the nipple and placing the hose clamping sleeve over the hose end section and by applying pressure in the line and pulling the sleeve and hose sections together, in an outward direction, the hose end section becomes clampingly secured between the clamping sleeve and the tapered outer surface of the nipple end section. To disconnect the hose pressure is removed and the hose clamping sleeve is pushed rearwardly to clear the hose end section which may then be pulled off the nipple end. In another embodiment, the clamping sleeve has a piston end located in a channel which is in communication with the pressurized fluid whereby the pressurized fluid displaces the sleeve in clamping engagement with the end section of the hose.
