Watertight container

Inflatable cushion comprising a watertight container adapted thereto, said container being provided with an eye for threading a carrying strap therethrough, said container comprising an upper and a lower hollow part each open at a front face and an intermediate piece whereby the container is provided with separated upper and lower cavities, the upper and lower part respectively being attachable directly to one another without said intermediate piece to form a cavity of about double size, the cushion being adjusted in its dimensions to the container so that it will fit into one of the separated cavities only when in a non-inflated condition in a folded or rolled-up form, the watertightness of each one of said cavities being maintained when the other part forming the respective other cavity is separated from the intermediate piece, said intermediate piece comprising a first transverse plane at a first end thereof and a second transverse plane at a second opposite end thereof, said cushion further comprising a hose attachment for inflating the cushion, said hose attachment comprising a shaft and a head which is thickened with respect to said shaft, said second transverse plane being provided with a recess into which fits the shaft of the hose attachment, whereby the head of said hose attachment is accommodated between the two transverse planes of the intermediate piece.
