If you are going to put a splice in the middle, it really should be in a metal handy box with a plain cover
Use Romex clamps to prevent the wire from pulling out and use some caulk to seal and holes. For good measure, run a bead of caulk around the edge of the cover before screwing it down.
You can't use Romex clamps on S/O cord. You can use these.
This would be better.
