The invention relates to a fastener for pieces of jewellery, comprising a hollow first closing element provided with a groove comprising an insertion opening and extending at least partially around the periphery of the first closing element. The groove is used to receive a fixing part of a second closing element which can be introduced into the groove of the first closing element via the insertion opening. The cross-section of the first closing element is larger than the width of the groove. The first closing element comprises a wall on two opposite end sections, said wall sealing the hollow first closing element. The groove extends into the end sections of the respective wall and ends therein. |
