Abstract: A magnetic jewelry attachment assembly for selectively coupling mechanical clasps at opposite free ends of an article of jewelry, including a pair of clasp-retaining cases magnetically-couplable to each other. Each clasp-retaining case incorporates an elongated clasp-retaining body having a clasp-receiving channel extending into a proximal end of the elongated clasp-retaining body, the clasp-receiving channel extending from a proximal channel end to a distal channel end, the distal channel end terminating within the elongated clasp-retaining body. A clasp securement device is provided mounted within the distal channel end of the elongated clasp body-retaining and configured for releasably-engaging a first mechanical clasp at a first one of the opposite free ends of the article of jewelry.

Abstract: A jewelry attachment assembly includes a pair of cylindrical cases. One case has a male section including an annular flange with a pair of diametrically opposing radial splines situated on its periphery. The other case has a female section including a hollow sleeve with a shell. The sleeve includes a pair of diametrically opposite channels formed in the shell. Each channel includes an axially extending slot and an adjoining circumferentially extending slot. During assembly, the male section of one case is joined to the female section of the other case by registration of the pair of splines within the pair of circumferential slots by first guiding the splines through the axial slots, then guiding the splines through the circumferential slots. A pair of opposite polarity magnets are housed in the cases and disposed in adjacent relationship to promote magnetic coupling of the cases.
