Abstract

Push-pull closure for a drink container comprising a body element which comprises a through-opening and a fastening device, with which it may be sealingly and releasably connected to an opening of the drink container, a mouthpiece which may be axially displaceably inserted into the through-opening of the body element and which comprises at least one locking portion which may engage behind the through-opening of the body element, and a locking element which may be releasably attached to the inner face of the body element facing the drink container, the locking element being arranged so that the locking portion of the mouthpiece may not adopt a position in which it does not engage behind the through-opening of the body element, when the mouthpiece is inserted into the through-opening and the locking element is attached to the inner face of the body element.
