Abstract
A spear tube comprises a body connected with a keg neck interface of the beer keg. A gas valve, a down tube and a beer valve installed in the down tube are fittingly connected to the body. A stopper prevents the spear tube from popping out from the beer keg during detaching operation. A stopper portion of the stopper is formed protruding in the obliquely upward direction to penetrate a side hole of the body and has a cross-section a predetermined curvature shape. Therefore, the stopper functions to prevent the popping-out of the spear tube and is improved in its durability.
