Loop-to-loop connection
Also called loop to loop, loop-to-loop, loop connection, leader loop connection
A loop-to-loop connection joins two lines by passing each loop through the other, then pulling tight. It is commonly used to attach a leader to a looped fly line or a sink tip to a running line.

What Loop-to-loop connection means
Two factory or tied loops get linked, then snugged down so the loops seat against each other. Many anglers use it at the front of a fly line to connect a leader, or between a sink tip and a running line on systems that use loops.
To connect, pass the line loop through the leader loop, then pass the end of the leader through the line loop and pull tight. The same steps work for tip-to-running-line connections.
It works best when both loops are clean, not twisted, and sized so they pass through each other easily. If one side does not already have a loop, anglers usually tie one with a perfection loop or build a loop with a nail knot method.
Why it matters on the water
This connection makes it practical to swap leaders or tips quickly without cutting back line. That matters when changing from a dry fly leader to a heavier nymph leader, or switching sink tips as depth and current speed change.
The tradeoff is bulk. A loop-to-loop hinge can catch on rod guides, and a rough or oversized loop can hang up more. Keeping loops small and smooth helps turnover and reduces tangles.

- LeaderThe leader is the clear, tapered line between the fly line and the fly. It turns the fly over and gives you a clean, controlled presentation.
- Nail knotA nail knot is a compact line-to-line knot used to attach fly line to backing, or to tie a butt section or leader directly to fly line.
- Perfection loopA Perfection loop is a small, inline fixed loop knot used to form a clean loop in leader or tippet material for loop-to-loop connections.
- TippetTippet is the thin, level line tied to the end of your leader. It’s the section you cut back and replace as you change flies and re-tie knots.
