I've broken a small plastic component in a shower fitting on the boat.

The fitting is normally in tension, but experience torque when the shower head is moved.

My first thought was super glue, but is there anything better?

Second thought was that there's not much hope of a permanent fix, but before I ditch the whole shower fitting (expensive) has anyone any advice how to tackle a repair like this?

It all depends on what the plastic is. I'll guess polystyrene, in which case a solvent glue like Mek-Pak should make a very good join.
 
Thank you, I looked up the baking powder and super glue trick, and I can see that it makes a super hard glue, but it's not clear whether it'll will stick to the plastic, or not.
I guess I'll only get one shot at this, has anyone any idea about how to tell what plastic it is?
Polystyrene as jumbleDuck suggest?

Bison hard plastic glue is another, depending on plastic, ABS or similar.

Try a little spot, or the back, see if it melts the plastic, or sicks and will not let you scrape it off, if it is wrong it will come of easy.

I use Tensol cement for Acrylic, but how it performs with styrene I am not sure. A contact adhesive is what would work best. It may be a good idea to add more plastic (glue in) to the inside as a support hopefully improves the strength of repair. Worth a try.
 
I emailed Bison's technical department, they advised Bison Power Adhesive, a 2 part polyurethane adhesive.
I've ordered some online and will give it a go when it arrives.
Thanks for the input, I hadn't heard of Bison or Tensol or Mek-Pak, so just getting these key trade names allowed me to search and find out more.
