The jougs, juggs, or joggs (Ol French joug, from Lat. jugum, a yoke) is an instrument of punishment formerly in use in Scotland, the Netherlands and possibly other countries. It was an iron collar fastened by a short chain to a wall, often of the parish church, or to a tree. The collar was placed round the offender's neck and fastened by a padlock. The jougs was practically a pillory. It was used for ecclesiastical as well as civil offences. Examples could still be seen in Scotland at the beginning of the 20th century. It may have lent its name to the modern "jug", slang for prison.
