Clean each side of the crack both top and bottom of the catcher plastic part with something like brake cleaner, carb cleaner, naptha, etc. Scratch up the plastic with some heavy sand paper for at least an inch either side of the crack. Grab your handy dandy soldering iron and melt the crack together. You can find some donor plastic of a fairly close plastic material to use as a filler.
After the crack has been melted back together, use some heavy two part epoxy or even a heavy two part glue like JB Weld. You can then place another piece of plastic on top of the epoxy and allow the original and donor plastic to become one. Should do the job for you.
