<p>A device and method for coupling a rigid pipe (12) to a flexible hose (22). The device for coupling a rigid pipe (12) to a flexible hose (22) is designed for use in low pressure applications whereby fluid communication between the rigid pipe (12) and the flexible hose (22) is prevented. The coupling of the present invention includes a clamping ring (30). After assembly of the coupling using the method of the present invention, a terminal end of the flexible hose (22) is interposed between the terminal end of the rigid pipe (12) and the clamping ring (30). Each of the rigid pipe (12) and clamping (30) is deformed to define cooperating annular rings, and to deform the flexible hose (22) therebetween. Deformation of the flexible hose (22) between the rigid pipe (12) and the clamping ring (30) annular rings serves to form a seal to prevent fluid communication between the rigid pipe (12) and flexible hose (22), and further prevents removal of the coupling. In an alternate embodiment, at least the rigid pipe (12) is deformed to define a barbed annular ring. In another embodiment, the clamping ring (30) is likewise deformed. In still another embodiment, the claming ring (30) defines a knurled surface (42) for increasing frictional resistance between the clamping ring (30) and the flexible hose (22).</p> |
