Lots of methods will work. Welder glue and goop are popular.
However, If you want the strongest joint -
1. flash the coro,
2. use a "woodpecker" to punch tiny holes in both sides to be glued
3. put small drops of CA about 1/2" apart on 1 side,
4. dampen the other side with a wet paper towell or mist with a spray bottle,
5. Clamp or weight the pieces for at least an hour.

These pieces will not ever come apart!
