There are some "insulation displacement" splices and taps that are rated
for 120V

I agree the best solution is to splice inside the fan.
I doubt the other splices indicated above are intended to be installed
exposed and to take strain in the cord.
How about installing a plug on the end of the cord and plugging it into
an extension cord.
