Abstract: A connecting device for connecting a water hose to an object. It includes at least two pieces, of which one is connected to the water hose and the second to the object. The first connecting piece consists of a hand shower, part of which is a handle and part a shower head. The hand shower contains a valve device having a valve body which is moveable between at least two positions, and which is designed to be moved to a connected position by means of the second connecting piece. The valve is designed to then allow water to flow from the hand shower to the object while preventing water flow out of the shower head; but the valve allows water to flow from the shower head when the valve body is in its normal non-connected position.
