Description
This small plastic piece can be added to the self bondage armbinder to prevent the zipper from coming down. The lock is slid onto the tether strap. It must be adjusted in advance of putting the armbinder on (it should only just make it through the d-ring at the shoulders when the armbinder is zipped all the way up. When it is pulled through the d-ring of the armbinder, it prevents the zipper from sliding down. It is an added level of security, the armbinder can be used without it as well.
