Kelvin clips this is necessary for low resistance measurements.
Most popular application for Kelvin clips this is battery analyzers, them able to measure from few milliohm up to few ohms.

This year one maker in Taiwan he came by this product design ( picture bellow).
I am posting this information purely for people like me, that we love to stay informed of new product ideas and of latest engineering.   ;)
Specific Kelvin Clips cable this is designed to operate with handheld analyzer.
Possibly and because cable length this is longer than 40 Centimeter, product designers add to it an extra (guard/earth) cable.

Very recently I become aware that at Kelvin Clips harness with shielding, their guard/earth point this is not an actual Earth ground connection.
There is no actual connection of guard/earth point this be over the equipment  with true Earth ground at metallic chassis.
Therefore such a guard/earth point at Kelvin clips harness, this serves in cooperation with inner product shields them be at the measuring circuit.
Practically all inputs of four Kelvin wires they are isolated from its other and all of them also isolated from Earth ground.
