Petzl EasHook ( Looks like they missed the Y from EasyHook!)
An amazing new concept of being able to semi-permanently install a connector onto any lanyard with just an Allen key! The gold section unscrews, allowing it to slot onto rope and webbing easily. Put the gold section back tight and away you go. The very easy to use double action gate allows very rapid connect and disconnect without ever having to remember your screwgates.
