Jacobin, If you do not mind about cosmetic appearance give it whirl and try repairing. Instead of just using a plain glue try a 2 part epoxy glue and use fiber mesh tape(dry wall tape) to back up/strengthen the repair. Tape off area that you do not want any glue on, mix up epoxy per instruction on product, apply a little to the broken section, apply the tape over the break and then apply a generous amount of 2 part epoxy over the tape. You can do a couple layers if need be. Would be really good if you can clamp to keep break tight/closed until cured. Some dollar stores may have the 2 part epoxy(syringe) and mesh tape. Good luck. I hope this helped you out, if so let me know by pressing the helpful button.
