If you can seam it together pretty well, I don't see why some very carefully placed super glue wouldn't work?

But be warned, everything melts that stuff. I mean, just about every chemical will melt it and make it cloudy.

Otherwise, maybe some clear silicon glue or the kind of stuff that is used for mounting the rear view mirror might be in order if you can get it lined up right. Put it along the seam, get out your tape, and glue it together.
