Abstract (en)
At each end a string of pearls is fixed to an eyelet of a plate or tab element having a raised elastic tooth. An end half-clasp for the string of pearls comprises a housing for the tab with an abutment surface for retention of the tooth. The tensile strength of the tooth is calculated to be less than the breaking strength of the string of pearls, so that the tooth yields before the string breaks to prevent the pearls getting lost. A box-like seal-of-guarantee is applied on the tab element when the latter is not yet coupled to the closing clasp so as to cover the tab element and the end knot of the string of pearls completely, in such a way that it is not possible to tamper with the one or the other without such tampering becoming clearly visible. It is preferably applied to the jewellery field. <IMAGE>
