The valve is comprised of a strip (1) on which are welded two coplanar strips (3, 4) separated by an opening (5). In order to fabricate the valve, a web (11) is used on which are welded two bands (12, 13), separated by a gap (5). The resulting valve (16) is welded onto a sheet (17) which is part of the inflatable body, is provided with an orifice (19) in registration with the opening (5) of the valve. Then, a second sheet (21) forming the inflatable body is welded to the first sheet. Said process provides for the production of a single-inlet double valve.
