A volume-flexible body fillable with a fluid including two sheets preferably welded together along the peripheral edges and preferably made of synthetic material, as well as a connection piece for a line for fluid inlet or outlet, preferably gas, especially air, into or from the body, whereby the connection piece ( 4, 10, 12 a) extends into the body (K) from the location of entry parallel to the plane defined by the peripheral edge ( 3 ) and possibly extending past the location of entry parallel to the plane defined by the peripheral edge ( 3 ) and leading through the edge and/or penetrating one of the sheets ( 1 ) and leading into the interior of the body (K). The connection piece ( 4 ) is provided with radial openings ( 5 ) whereby the connection piece ( 4 ) extends completely through the body (K) and leads again to the outside through the edge ( 3 ) at a point opposite the place of entry to improve inflation and deflation capability and to maximize additionally the usable surface and/or to accomplish installation in the best possible way.
