Instead of splicing, add a new plug on the piece of the cord with the receptacle and a new receptacle on the piece of the cord with the plug.
Accidentally cut your good, heavy-duty extension cord? Replacement cords are expensive, and you can save money by just repairing it.
Technically, you’re not supposed to

Instead, if both sections are long enough to
be worth saving, just buy a high-quality
plug and receptacle and make two
cords out of one. Be sure the new ends

old cord and that both have built-in
strain relief clamps. Otherwise, just
buy one end and accept the fact that
your 100-ft. cord is now only 92.56 ft.
