What is the best way to connect the loose end of a new pigtail on temp sensor? on 1993 Pontiac Grand Prix

I am replacing the coolant temp sensor and pigtail and need to know what the best way is to connect the loose end of the new pigtail?

BEST way is solder with heat shrink.... See YouTube!.... Can use solder-less crimp connectors with electrical tape... If still unsure... See mechanic!!
sorry i thought you the lock clip was broken. oops
That's what I figured... That does work good on the other end for broken connector!!
