Is there a safe and accepted (NEC) way to splice/connect two regular electric cords/wire where the connection is not inside a box ? I have a need to make a number of splices with regular extnsion cord type wire (reasonably heavy duty) and it would be much easier if there is some type of clip on type slicer. The lights came with clip on type plugs....is there a similar splicing clip for connecting the wires
Thanks, TR
