Oh my...  Good GOD no...  Those things are terrible!   :scared:

That kind of horrible thing is never allowed in any kind of permanent wiring installation anywhere here in NA, at least not that I'm aware of.  I certainly would never use those anywhere, even inside some solid steel kitchen appliance or industrial apparatus that couldn't possibly burst into flames.

Actually, most US wall receptacles currently being sold have a connection like that.  It's packaged differently, but the principle is the same.  It was up to 12 AWG, but now they only allow that connection for 14 AWG.

From what I've been able to tell, most of them are pretty terrible. There are good spring connectors, and then there are bad ones.

I will own up to having used them on one recessed outlet to power a TV, because it turned out the breaker was mislabeled and a long walk away.. easier to just poke it in than try and bend a live wire around those screw terminals.

I'm not sure I've ever used one.  I prefer to bend wires around screws.  Though I have worked on outlets where they were used to add another circuit leg.

If you can press it with a finger like in this picture, it is not the kind of connector I would go out of my way to put in a circular saw. >:D Even a very small screw can generate a lot of force compared to that. Even solder and heatshrink would be better for vibration, IMO.
