Reference for LCR or ESR meters

I see what you mean about the need for the test clips to bite into the component under test's leads to get a stable measurement reading. Just as a very quick test I modified a pair of standard grabbers to make them into makeshift "kelvin clips" for my TL-21. In theory, I think that these things should work better than the standard TL-21 croc clips, but they didn't... (see update)

I'll keep my eye out for a true kelvin clip that can supply the needed solid grip onto component leads to get the result that I am looking for when measuring low milliohm values.

My Rube Goldberg "kelvin clips" are at least good for a chuckle...

UPDATE:
I only made this rudimentary set of "kelvin clips" from two standard grabbers I had on hand so I could see if the slight instability in my low milliohm measurements was the DE-5000 itself or because of the TL-21 crock assembly. I also made a simple adapter out of a piece of double sided copper-clad material and a bit of lexan so I could plug these "kelvin clips" into the LCR meter without modifying my TL-21 accessory (added two photos below). The copper-clad material has the four required isolated zones cut into it for doing true four wire measurements.

To my surprise the readings are very steady now. At least I know now that the LCR meter itself is fine. I'll modify my TL-21 when I purchase a pair of proper kelvin clips, using shielded cable.

Nothing wrong with that design   I am sure the residual on that is smaller than the meter can detect.

Agree with Robrenz on a non serrated jaws, apart from the slippery, the "sharp teeth" of the serrations also good for biting into oxidized surface at the pins to have better contacts.

Anyway, that Rube Goldberg kelvin clips look awesome, pretty sure it will work just fine. 

Just for your reference, pictures of the Kelvin clips from the MS5308 standard accessories attached below, not the same league as Agilent's  or worst compared to the ones made by Robrenz  , but I think these clips are decent enough to do the job well.

robrenz & BravoV... thanks for the kind words. I added an update with two additional photos to reply #50 above. My temporary "kelvin clips" enable very solid low milliohms readings now. At least I know now that the DE-5000 itself is fine. Also, I like the look of those kelvin clips from the MS5308.
