Help....Shower Question ? - uk rubber shower attachment

Hello guys.

We really appreciate your help.
I bought it yesterday

He is the one with the rubber stopper placed on the taps / faucet. Well, when you tap to steal spray, rubber connectors, or.
I think it has something to do with the water pressure, but I do not know what to do. I asked my father for help, but I think my dog knows more than he.
So guys, if anyone of you know what I do for it to work properly, I would really appreciate it.

Thanks
