When watering the plants on a larger grave area or a wide bed the pipe extending from the container of the watering can is often not sufficient to reach the plants at the far side. A water hose is not always available, bending the body forward not healthy and in case of elderly people even dangerous. The extension pipe can be simply pushed onto the outer end of the normal pipe. The slightly tapering shape facilitates the use of the ordinary rose attachment and can be fitted with a lateral handle.
