Anybody know what this is called, so I know what to order!

I had a similiar problem with the 3 way fridge knob, it split just as yours did, I had an 8mm gas compression fitting and took the compression collet from it, I used a vice to gently push it over the split part of the knob and has worked perfectly for the last 7 years.

Quick update! So I had previously sprayed loads of WD40 to try and free the valve which didn’t work. This morning I tried Duck Spray on the valve left for a few minutes got the mole grips on the valve and cautiously tried to turn the valve, which it did with minimal force. The valve knob easily turns the valve now and I’ve glued the crack, so hopefully all is good! I remember an old neighbour who swore by Duck Spray!!!

If the valve is now freely moving, then to assist the repair to the knob wrap wire around the split spigot, fit a small jubilee clip, or even a cable tie around it to offer it more support than just the glue. If that makes sense.
