That's a beech, mon! I have used soda straws to support a weak or broken stem. I keep thinking if you take two pieces, cut them to length and cut a slit up lengthwise, you could put two splints around the stems (the upper limb and the broken limb) and tape them together maybe. If you have that much of the 'skin' intact, my guess is it could be just fine in a couple weeks. Take the splints off later if you have to, or just leave them on till harvest.
Good luck Pops
