Some earlier plugs were like that. These days, there is a hole in the
end of the pin, and a grubscrew into a threaded hole at right angles
that clamps the wire. Remember the wire is thinner over here.

And of course, nearly all of our plugs have fuses in them. A 15A breaker
is not too good at protecting a 5A flexible cable to an appliance.
