A countersinkable tap for liquid containers is provided. The tap includes a tamper-evident device. The tap includes an outer tube having an abutment which bears against the can wall and adjacent to which is a sealing ring which seals off the can orifice. The tap also includes an inner tube mounted rotatably and displaceably in the outer tube, with a grip and with orifices to allow beverage flow out of the can interior through the outer tube to the inner tube. The inner tube has a spigot which engages into a radially running slot of the outer tube. The outer tube includes a wedge punch and the grip possessing a tab which covers the wedge punch and onto which is integrally formed an inwardly directed thickened portion which, when the grip is rotated, slides on the wedge punch and opens the tab to indicate tampering.
