An apparatus includes a cylindrical housing for fitting about a spigot. The housing has a first bore extending along a partial length thereof and a first end. The housing further has a second bore, abutting against the first end of the first bore, which has a lesser diameter than the first bore diameter. A cylindrical sleeve includes a bore extending along a partial length thereof, a rough outer surface, has opposed ends, and has a length less than that of the housing. One end is engageable with the spigot. The sleeve is engageable within the first bore such that another end thereof abuts against the first end of the first bore. Another sleeve end includes a lip portion extending inwardly therefrom. A mechanism is included for securing the sleeve and housing to the spigot such that the spigot is rendered inoperable while the sleeve and housing are connected thereto.
