This invention deals with a clasp that was first thought of as an adjustable clasp for necklaces, bracelets and rings. It can have a valid job even in other sectors because it allows for the union of two strips, or of the two ends of the same strip. This is as long as they are made of a rigid material and are welded according to a series of loops alternating transversally.In fact the clasp, by and large, consists of three bars that, hinged transversally to one end, are stopped by a trigger, in a parallel structure. It blocks two strips over the top of a section of one curve and two counter-curves, or a fold and a counter-fold.
