A device that can be locked onto a person's [[penis]] to prevent the wearer from engaging in sexual contact. In many cases, it also makes erection uncomfortable or impossible. Also known as a penis cage. It is used as a [[sex toy]] as a method of erotic sexual denial.

Not to be confused with a [[chastity belt]], which serves a similar purpose, but wraps around the wearer's entire waist instead of just the penis.
