Convergent invention; I had not seen those for some reason, as soon as I posted elsewhere someone else pointed out what they make. I think their wire is welded to the sides of the threaded section - I did that for the first few but silver soldered, then somebody worried it might not be strong enough so I started cross-drilling and bending the wire 90 at the ends; more work but more secure.
