how to strongly secure a wire over a couch frame to stretch seat spring webbing

I have a wire piping that used to be secure around the frame perimeter of my couch base so that a flexolator webbing with springs would be stretched taut and clip onto it. However, this piping has come loose and the wire that used to secure the piping frame has broke so now the webbing sags. I’d like to clip/secure the piping so that it can be strong enough again to clip on the springs to it. I tried heavy duty staples but that was too weak against the pull. What is the best way to secure the piping back onto the frame to withstand the force of the springs and stretching when it clips back on.

Similar to this photo, the springs clip into a cable/wire/piping that goes around the frame.
