terret

A terret is a small circular or oval metal ring that is attached to a leather strap on horse harness equipment. Its primary function is to serve as an anchor point for reins, traces, or auxiliary straps, allowing components to be attached, adjusted, or redirected without slipping along the strap.

Historically, terrets are found in a range of harness configurations from antique to medieval gear. In archaeological finds, they are identified as ring fittings on bridle, breastpiece, or yoke assemblies, indicating how reins or attachments were connected to the horse’s gear. The form and size of terrets can vary, with common materials including iron, brass, or steel, reflecting available metallurgy of the period.

In practice, a terret provides a stable point of connection while accommodating movement of the animal and the harness. The ring can act as a guide for a rein or as the anchor for a strap that transmits force from the animal to a particular part of the harness. While terrets are most commonly discussed in the context of equestrian equipment, the term appears in museum catalogs and historical catalogs as a way to classify these ring fittings across different harness sets.

Etymology-wise, the word terret is of French origin and has been retained in English to describe this specific ring fitting. See also horse harness, bridle, reins, and traces.
