Are you refering to the conductor going "straight" into a "hole" at the back of the device, and then you tighten the screw which compresses the "hole" tight??
That sounds a fair description. Here's a typical device:

You can't see the line & neutral terminals for all the plastic surround, but they're the same type as the exposed grounding terminal.

Some of the more expensive versions have a "square" hole and instead of the end of the screw itself clamping the conductor in place, it compresses the wire(s) under a small square plate.

(No, the plate on the device isn't actually blue, it's just poor color rendition!)
