Depends on the location of the break.
Plastic weld if you've got the room, just use a soldering iron and a cable tie as your weld material.
If it's a tight spot then perhaps a bit of ordinary Loctite super glue, with some metal or extra plastic material placed on top to brace the broken part.
If it's a part that doesn't need to be held solid, then I've also used polyurethane sealant. Think of it as a rubber glue.
