My wall power outlets at home do not have a center screw. Some 6 way splitters have a center hole so you can secure it to the outlet such that it won’t pull away when you unplug something.
So I made this. It uses the existing screws from the wall plate.

+1 - I’d like to see the unadorned splitter, so I can better visualise the problem.
As you can see, besides the friction of the metal prongs/contacts that gets plugged into the sockets, nothing is holding it in place. So if I try and unplug something, it’ll pull the whole thing out.
I think I understand the problem, but I’m not a yank, so I don’t know the type of splitter you’re using/talking about. Just wanted to see it without, to better appreciate the design.
