The knot is named after the Kalmyks, a nomad ethnicity in Russia. It is very quick to tie, it is secure, and it undoes quickly when pulling the free end. The knot isn't mentioned in The Ashley Book of Knots but in its Russian equivalent, the book "Морские узлы" by Lev Skryagin (1930–2000).
Without the slippage the knot is known as Cossack knot.
