Various connectors ... Wago, In-Sure, etc ... are available. They seem to be much more reliable than the "back-stab" connections on receptacles. hey actually seem to be working in the 'real' world.
A couple of cautions, though:
- All of these connectors need clean, straight wires in order to make a good connection (no 'used' scored and twisted wire, please!); and,
- Most of these connectors have no way to remove the wires, short of destroying the connector.
