A tank installation comprising a tank having at least one flexible wall arranged to rest on a rigid apertured partition, which per se does not form part of the invention. A flexible duct is joined to said wall and is intended to pass through the aperture in the partition. One end of the duct is connected to the flexible wall of the tank by a folded-over portion located inside the tank, and the other end of the duct is arranged for connection to another device that is to be placed in communication with said tank. The other device may be a second tank which also comprises a flexible wall with a flexible duct substantially aligned with said flexible duct of said first tank, and the extremities of said two flexible ducts are joined to a rigid pipe. These two tanks may be adjacent, the flexible duct of said second tank being directed towards the inside of the second tank and the rigid pipe is located within the second tank. Alternatively, the flexible duct of the second tank may be connected to the second tank by a folded-over portion located in the second tank, the two tanks being spaced apart from each other. In another embodiment, the other device is a rigid pipe. The flexible ducts are secured to the rigid pipes by clamping collars.
