1. A container closure comprising a base portion extending about a reference axis of the container closure, a cap portion which in a closed position covers a drinking opening of the container closure and in an open position leaves the drinking opening of the container closure open and a tamper-evident ring made of an element inde-pednent from the cap portion and base portion, the tamper-evident ring being positively connected to the cap portion and hooked to the base portion and having a breaking zone which breaks when the cap portion is opened and causes a non-reversible and visible change in the container closure, wherein the tamper-evident ring, for form-fit connection with the cap portion, has an annular bead which is not radially covered by the base portion and extends into an annular groove of an outermost wall of the cap portion which points radially outwards.
