Like D-fi said, just stick the end of the core line in to the PVC bell end and glue it. I've done it a bunch and it works great.
I'd much rather use core line in the walls and concrete than PVC, just make sure you keep it tight and tie it often so when the concrete is poured in to the wall it doesn't break it or make it so "wavey" that it's tough to pull through. Lots of ripples will make it really tough to get a fish tape through. ...Steve
