By hand, tie an underwriters knot in the cord.

Also by hand, connect the wires by wrapping them clockwise around the screws and tighten and connect the neutral wire to the silver screw.

An underwriter's knot prevents the wires from pulling out of the screw terminals when cord is tugged. ( The entire process of tying an underwriter knot can be done by hand . Form a loop using the first wire. Then, form a loop around the first wire and pass the tail through its loop. The strain on the cable is now taken by the knot.)
