Device for tapping containers filled with liquid, in particular, tin cans filled with beer, with a mounting for fixing the device relative to the container, with a tubular piercing member sharpened at the front which penetrates the wall of the container, with a tap arranged on the tubular piercing member, and with a sealing collar enclosing the tubular piercing member and abutting against the container wall. The tubular piercing member is immovably connected to the mounting, and, when the latter is positioned on the container, penetrates the container wall. The sealing collar protrudes beyond the cutting rim of the tubular piercing member so that when the device is fixed on the container, the sealing collar abuts against it sealingly before the tubular piercing member penetrates the container wall.
