What product can we buy to hang our shower head - without requiring drilling?

We have a bathtub with a handheld shower nozzle (looks like an old fashioned telephone). We would like a way to hook/hang it up so that we can rinse our hair with two hands! But we rent our flat and can't put holes in the tiles. Is there a suction or footed product that we can get to hook up the showerhead? Thanks!
