Yes, there is, it is closeable belt to save the wives chastity in absence of her husband (15.-19. century)." It is a mechanical device which prevents its wearer from having sexual intercourse. The classical version for women consists of a metal belt and a metal band runnig trough the legs with a hole for urination and a hole for defactation. The belt is closed and connected with the band with a lock. There are newer models, consisting of a metal belt, a shield covering the vulva, connected to the belt, and one or two chains attaching the shield with the belt, the chains running over the buttocks, or the chain running between the buttocks, dividing the faces in two parts. The shield has a hole or a slit for urination. Sometimes a second strap covers that hole to prevent masturbation. Sometimes the whole thing has also the possibility to add one or two plugs, entering the anus respectively the vagina, which can't be removed as long as the belt stays closed. A cheaper version is not made of metal, but of leather or another cloth material. Those versions usually have no holes for using the toilet, and they can be destroyed with scissors. For woman, there are also metal bras wich can be locked, and I saw also a pair of metal tighbangles, chained together so that the woman wearing them was unable to spread her legs.
