I have a double wire back to the trailer chassis - one just goes tight when the bow is against the snubber, the other is slightly looser. Both are held held with the small U- bolt clamps. Theory being the first one on it's own is unlikely to stop it (and if it did would transfer all the energy straight back into the trailer & thence through the hitch to the back of the car)
The idea of the multiple clamps / wires is that the energy is dissapated a little less suddenly.
Hopefully I'll never get to test it for real.
