GLUE for ripped-off bumper piece??

Ok, some1 JERK threw a box out of his/her window on the highway, it came barrelling down and hit my front right bumper (Sport P.) The very tip of it is sort of hanging off, but can easily be shoved upward to fit the crack:

SO: I want to glue it back on for the time being (as i'd have to replace the ENTIRE front bumper)

What glue/adhesive do I use? I tried SuperGlue, but that didn't work at all.

any ideas?

thanks.
