A plastic snap hinge closure having tension elements disposed on a plastic closure including a lower part and an upper part which are connected with each other via a main hinge A desired snap effect is achieved by means of lengths of the tension elements which can be changed by the action of a pull. The tension elements extend in planes between the attachment points. Each tension element has partial sections which cause the change in length. The partial sections are either C-shaped, U-shaped, or O-shaped. The tension elements permit a maximum percentage change of length of each tension element of approximately 10% to 50%.
