Abstract
A flexible winding hose coupling apparatus is provided which allows for the rapid coupling of a flexible hose thereinto. The coupling can then be attached to another hose or to a pipe fitting or tap. The coupling has first and second coupling members with the first coupling member having a hollow tapered bore therein and the second coupling member loosely fitting or floating in the bore of the first coupling member. The first coupling member has an annular ledge formed in the bore to act as a stop for the second coupling member and has a plurality of annular barbs formed along the bore walls. The second coupling member is located in the first and has an external taper thereon with a plurality of external annular barbs therearound so that sliding a flexible hose over the second coupling member expands the end of the hose along the taper and over the barbs, driving the end of the hose towards the inside of the first coupling member bore walls. The enlarged hose seals when an internal hydraulic pressure is applied thereto or with a reverse pull on the hose, once the hose is pushed over the second coupling member, by the second coupling member and hose thereon sliding toward the tapered barbed internal wall of the first coupling.
