Simple connector for single conductor 0.75mm² (18 AWG) that will remain connected under tension while being spooled (lemmy.ca)

I have a 750m 0.75mm² wire on a spool that needs a quick disconnect connector of some sort on it so it can take it off in 250m lengths. But it has to handle the tension of being spooled up. Any ideas?

In an ideal world it would be a male and female banana plug thing, but that wouldn't hold under tension. So I'm hoping you folks have ideas.

Have you seen these knife connectors used in aviation? They are genderless and lock together. Of course your crimp better be solid - meaning proper connector for the wire size and proper crimping tool die.

No never seen them. Will investigate. I wish the pictures made it more clear what the actual mechanism is. Maybe I need to handle one in person to understand.

They are kind of like two hands making a handshake - they just twist/slide into each other and each is then looped around the back of the other. Very simple and effective
