ABSTRACT:
A tap for a beer keg having a Sankey-type fitting with radially inwardly extending lugs which normally are used to hold a conventional tap in a locked position on the keg. To prevent the locking lugs of the fitting from being damaged or to permit use of the keg after the lugs have become worn or damaged, the present tap includes a radially expandable and contractible collar adapted to lock onto the external lip of the fitting. The collar is formed by two camming clamps connected to swing about a hinge and adapted to float angularly relative to the body of the tap in order to permit the clamps to center themselves on the fitting. As the clamps are closed, they cam against the external lip of the fitting and force the tap downwardly to open the valves of the fitting.
