Loosen the two screws at the cord side and then see if you can pull on the plastic edge that sticks up a bit where the end touches the metal and see if it moves at all, also try twisting it to see if there is any movement.
Worst case scenario would be you break the wires from the connection but you should still be able to figure it out.
I've run into some old plugs that didn't have the set screw I seem to remember they just were held in place by tension but it's been such a long time I can't quite remember and I know I threw them out and replaced them.
