Halter hitch (quick-release hitch)

The halter hitch is a slipped overhand tied around the rope's own standing part. Instead of passing the end right through the loop, you pass only a bight of it. This bight acts like a bolt: as long as it sits in the knot, everything holds; pull it out and the knot collapses.

A pull on the standing part tightens the overhand around the bight. A pull on the loose end, by contrast, draws the bight out of the knot, and because it is the only thing holding the knot together, everything releases at once. That is why the knot still opens while the line is under tension – though not always easily under a heavy pull.

On the finished knot you see a small overhand around the standing part, with a bight and the loose end next to it sticking out. If there is no curve of a bight to be seen, only a straight end, you have tucked the end instead of a bight – then the knot no longer releases with one pull.

Dress the knot, snug up the bight and the standing part, then slide the knot up to the ring or rail. The loose end should be long enough to grab securely, but not so long that it dangles, snags or gets pulled by accident. Test before use: pull the standing part (it holds), then pull the end (it opens).

The knot is ideal for anything made fast only for a while that may need to be freed quickly: a pack on a railing, a line on a ring you will need again soon, a tarp you want to take in quickly if the weather changes. It is quick to learn and one of the most useful everyday knots.

It is not suitable wherever nothing must come loose by accident, or for larger loads. A passing branch, a curious child or an animal chewing the end can open it. If that would be a problem, pass the end through the bight as well – then it no longer opens by itself, but also not with a single pull.

A line must never be knotted around the neck of a person or an animal. Anyone who wants to tie up animals follows the expert guidance for that animal and the regional rules; this page does not teach animal handling. Never leave tied animals unattended.

Under a heavy pull the knot can tighten so much that the bight is harder to pull out. A quick release only works if the knot is tied neatly and has not jammed – so test it regularly. The halter hitch is meant only for light to moderate, non-critical loads. Life-safety use of knots only after proper training with certified equipment.

The knot takes its name from the halter, the headgear of horses and other grazing animals to which a lead rope is attached. The slipping principle – tucking a bight instead of the end – can be applied to many knots, for example the round turn and two half hitches or the sheet bend.

A chair back or a railing is good for practising. Tie the knot, pull the standing part, release it with one pull, and repeat until it works without thinking. Practise it with your eyes closed too: in the dark or with cold fingers, releasing must work just as reliably.
