I've not heard that name for those before.

We have one situation in this house where one of those actually came in handy. There's an outlet in the laundry room with the washer and a refrigerator plugged into it. Both of these came with right-angle plugs, and it wasn't possible to plug the one into the top outlet safely because the right angle orientation of the cord interacted with the plug in the lower outlet. So one of those was used to offset one plug to be a little further out from the wall, and therefore usable. Of course the ground _is_ connected to the screw...

I should probably check and make sure that outlet does have a ground connection, some of them don't in this old house.
