Connector system between 12 GAUGE speaker wires


Aloha again!
After the highly appreciated top suggestions here:

https://forum.audiogon.com/discussions/scratchy-sound-from-tweeter
I am now stuck with: 

how to put a connector system between the last 3 foot of 12 GAUGE speaker wires that run inside the speaker stands to 8 GAUGE wire to connect to amp.
I find plenty of banana connectors but NO female ones. I do not like to use flimsy RCA connectors.
What can I use to quickly connect and de-connect my speaker stands (on rolls to move aside if in the way)

I wonder if there is any solid system out there?
Can I pair banana connectors with kind of binding posts?
Any suggeestions?

ieales, thank you so much for the link, this looks like my solution.2 of them and 8 banana plugs and I am good to go.
I hope that this project will not have a negative effect on the sound quality...but I can live with 5% less (:-)))


Thank you all again, I settled on the solution member ieales suggested and hope the order arrives soon and all will be good.

Happy listening!
