Adding a T tap to the 221 Inline Splice series

Thank you for your quick response.
My quest is for a T connector, similar to the Insulation displacement connectors. Where there is a through wire and the ability to have a branch wire off the connector. As you can see from the picture, I cut the red negative and black positive wire, use the splice connector and add a smaller wire for the branch. Most of the branches are separated from each other by some distance. So, a central distribution setup is not practical.
The voltage is all 18 volts for a model railroad.
What is I need designed is a splice with a third lever for the branch, otherwise I will have to bend wires around to continue the main wire.
Or a way to electrically join the splice with another lever nut.

I hope I have been able to present this clearly.

Thanks again for your quick response.
