I have a fairly cheap shower with plastic windows.
One of the knobs holding a shower window to the top rail
has broken.

The part that is broken is a hard plastic "washer",
1in in diameter and 1/4in thick.
The two parts fit together pretty well.

I tried sticking them together with UHU contact glue,
but this came apart again almost at once.

What is the best glue for this purpose?
Is Superglue appropriate?

Any advice or suggestions gratefully received.

Get a replacement from the manufacturer instead.

If it's PVC, PVC pipe cement. You need a solvent weld to keep anywhere
near the same strength, not a glue.

Presumably it has split apart roughly across the diameter.

If you really do have to repair it, it will probably need a bit
assistance from a 'strap' around the circumference. As it's 1/4" thick,
you may be able to file a groove around it, so when the two halves are
put together, it resembles a pulley wheel.

If it is hard plastic, superglue may be suitable basically holding the
two halves together. The 'strap' could be several turns of thin, bare
(and tinned?) copper wire (stripped multi-strand mains wire?) with the
final join being twisted and given a quick spot of solder. You can then
fill the groove up with more superglue (or polyester resin/paste), and
when hard, finish it off with a touch of sandpaper. It will then
probably outlast the other knobs!
