I'm starting to think I have dreamt this but... wasn't there an IBM Ethernet cable with instead of the little tab ending in ... nothing, it was a little bridge that went back down, so nothing to hook/snag on. But it didn't look quite like the 3D printed one here, but it was symmetrical looking, like a tiny tiny arch bridge.
Oh, and it was made of springy metal, in this maybe dream.
Pretty sure I’ve seen a version of this cable that had a solid tab that bent in the middle. I have no idea what the brand/name is, and just spent way too long looking for it. It wasn’t metal, but sounds like a plastic version of what you’re talking about. I remember really liking them.
