I've got a shower hose which has split where it joins the head. The
other end is buried inside the bath (via a none too waterproof grommet).
The simplest repair is to get a new shower hose (and probably head) and
connect the two 11mm tubes together. I'm having difficulty finding the
right connector though. I think what I need is an 11mm version of this:

Looking pretty is not a requirement, the whole installation will be
replaced next year.
