"Plasterboard fixers". They are either plastic things with little barbs that expand behind the hole and take a normal wood screw, or steel with a pair of little wings that expand when you tighten a threaded bolt. I have about a hundredweight of books above my head right now on glass shelves that are held up with the plastic ones (and some non-expanding plugs for points where I found I was drilling into wooden battens behind the plasterboard).
Now maybe you can translate "ACE" for us...
