Abstract

A valve body is provided with a locking post formed with the valve body to extend externally of the body generally parallel to the direction that the valve stem extends; the locking post and valve stem are provided or shaped with surfaces that enable the reception of a locking pin which can be inserted into a locking position by a user manually or with the aid of a tool supplied by the manufacturer of the locking pin or device; the valve mechanism will be tamper resistant in use in view of the absence of sufficient leverage to turn the valve stem by hand.
