This is what I've learned from a couple of wiring devices catalogs.
The devices that allow the stripped solid wire to be poked in the hole and held in place with a spring-loaded contact are called "BACK STAB"
The devices that clamp the wire in place under a screw are called "BACK WIRE".
I really really like back-wire devices. Bending hooks and looping over a terminal screws can sometimes be a pain....
