A knot for forming a tightening loop in the middle of a thin fishing line. This knot can be used to create attachment points for leashes on the main fishing line. A significant drawback of this knot is that when tying it, you need to pull one of the ends of the fishing line through the knot. This does not allow tying such a knot on already assembled gear. To do this, use nodes [Alpine butterfly](https://fishplanetapps.com/apps/fishing-knots/knot/knot-1378) or [Hanging (dropper) loop](https://fishplanetapps.com/apps/fishing-knots/knot/knot-1386)
