I have to wonder how many of the respondents actually looked at the item in the OP?
It is not a crimp connector. It does not have any knives that cut the insulation. I would not advise trying to make a “hot splice” with them. These are characteristics of the Posi-Tap, which is a different connector from the same company.
I have not used the Posi-Lock, but if they were available and I needed to splice two braided wires, I would prefer them over either the “metal tube” crimp connectors or the clam-shell locking connectors.
