Awaiting Repair

CyclopsJnr's toys have a hard life, and there is usually a queue of items awaiting repair in my office.  I've already tried fixing this Bakugan twice, but the very narrow bit that has broken is subject to a lot of torque and the glue hasn't held.  I'm going to have to figure out how to glue on a sliver of plastic to braceit without either obstructing the mechanisms or getting glue in the works...

It's a challenge...
