I would use quick cure urethane, available from windshield places. A tube costs $8-10 and will be more than you will need but the stuff sticks to everything. You will need a standard caulking gun to dispense it. Make sure both surfaces are clean, put a bead on one of the mating surfaces put together and have something to hold it in place while curing. It should be good to go after sitting overnight. This is very messy stuff if you get it on other surfaces but cleans up with automotive gun wash.
