I don't know if this lick has already been transcribed elsewhere, but I really like it, and it's not too hard to hear and copy without any tab or music.
It starts with two bars of descending chromatic notes, starting at G at the 12 fret and alternating in kind of a stutter pattern between fretted and open notes, much the same idea as he used in "Minor Blues" ... see Andreas Oberg's "Gypsy Fire" pg. 10.
Then he answers that with a two bar pattern that he plays at frets 10 to 13 on the D, G and B strings that includes some typical Django left hand ornaments on the G string with two fingers before an unexpected ending on the second string C to A.
It's not hard and it sounds great. Try it at half speed first, you won't have any trouble.
Paul Cezanne: "I could paint for a thousand years without stopping and I would still feel as though I knew nothing."
Edgar Degas: "Only when he no longer knows what he is doing does the painter do good things.... To draw, you must close your eyes and sing."
