PCT No. PCT/EP92/01495 Sec. 371 Date Mar. 10, 1993 Sec. 102(e) Date Mar. 10, 1993 PCT Filed Jul. 3, 1992 PCT Pub. No. WO93/02584 PCT Pub. Date Feb. 18, 1993.The connection element (2, 3) according to the present invention comprises a housing, and is capable of forming a symmetrical body such as a sphere (1) in cooperation with a second, essentially identical connection element as a result of the assembly of said two elements in mutually upside-down orientation. The interface portions between the housings of the two elements (2, 3) comprise portions which are cut in a plane parallel to the axis of the sphere, which axis is defined as the line which passes through the two opposing fixation points of the sphere to the ends of a necklace or the like, as well as portions which are cut in a plane which is inclined with respect to this axis to permit maintenance of the engagement of the two connection elements even under the application of a traction force onto the two fixation points. The elements according to the present invention comprise also two flexible pins (6, 7) which permit to maintain two connection elements in their respective engaged positions. |
