Double overhand noose
The double overhand noose is a very secure hitch knot. It might be used by cavers and canyoneers to bind a cow tail or a foot loop to a carabiner.[4][ [File:Noeud double gansé.jpg|thumb|Double overhand noose binding carabiners.[lower-alpha 1][lower-alpha 2]]]

Details
Make a bight
Turn around the standing end
the 2nd round rides the 1st
Tie inside the two rounds
- Tighten
A heavily tightened double overhand noose will jam. The bound object has to be removed before untying.
As the double overhand knot, it neither slips nor turns around. However, a third round turn might be useful with some highly lubricious spectra/nylon ropes.[5]
