The invention relates to a folding buckle clasp for a strap (2) of a timepiece (3), which can take up a closed position for keeping the strap (2) around the wearer's wrist and an open position for removing the strap (2) from the wearer's hand, the clasp (1) being provided with a flexible locking member (4) comprising ends (5) that are mounted in a pivotable manner with first and second folding leaves (6a, 6b) attached in a hinged manner to first and second strands (7a, 7b), respectively, of the strap (2), said flexible member (4) being defined to keep the first and second leaves (6a, 6b) folded in a locked manner in the closed position of the clasp (1) by having two components (8a, 8b) connected together by an elastic connection (9).

Clasp assemblies for bands (e.g., for watches) are disclosed. In some embodiments, a clasp assembly may include a plurality of pivotally interconnected links, where respective links are releasably coupled to one another, and spring assemblies disposed between respective links impart biasing forces between the respective links. In some embodiments, a clasp assembly may include a clasp body, a clasp cover, and a connecting arm pivotally coupled to the clasp body at a first end of the connecting arm, and pivotally coupled to the clasp cover at a second end of the connecting arm. The clasp assembly may include springs, magnets, elastomer members, and/or other mechanisms, components, or assemblies that impart a biasing force between the clasp body, the connecting arm, and/or the clasp cover.
