The locking parts 4 and 6 are internally fitted with magnets 10 and 12 polarized so that they attract each other when the locking parts 4 and 6 are joined, as shown in FIGS. 1 and 2. The end parts 8 and the locking parts 4 and 6 may be designed with complementary screw threads or glued faces 11.
[0049]In FIG. 2 is shown with dotted lines that the locking system 2 may include a tubular part 14 which is for disposition between the end parts 8 externally of the locking parts 4 and 6, and which has a radial connecting eyelet 16. In FIGS. 4-12, respective parts are designated with the same reference number as in FIGS. 1-3.
[0050]The locking system 18 shown in FIGS. 13-15 is constructed in principle entirely corresponding to the above described locking system 2, as the locking system 18 has a locking part 20 of the female type and a locking part 22 of the male type. Both locking parts 20 and 22 are provided with loose end parts 8 with connecting holes 9 serving for passing through of a cord of a piece of jewelry, for example, a string of pearls. Both locking parts 20 and 22 have internal holding magnets 10, 12.
[0051]Furthermore, the locking part 20 is provided with or designed with supplementing internal locking pins 24 which are disposed diametrically opposite each other, and which are adapted to interact with external locking grooves 26 formed in the locking part 22, so that the locking parts 20 and 22 may be interlocked by mutual rotation. In FIGS. 16-22, respective parts are designated with the same reference number as in FIGS. 13-15.
[0052]The locking system 28 in FIGS. 23-25 has a locking part 30 of the female type and a locking part 32 of the male type. Each of the locking parts 30 and 32 are connected by screw threads with loose end parts 36 with a centrally projecting tubular connecting part 38. Each of these are intended for externally receiving a part of jewelry, for example, a first pearl of a pearl string, the carrier cord of which runs through the tubular connecting part 38 into locking parts 30 and 32 and is fastened in end parts 36 by means of suitable fastening means, for example, glue or knots or a combination thereof. The locking parts 30 and 32 are provided with internal holding magnets 10, 12 and with supplementing locking means in the form of an external locking pin 40 on the locking part 32 and a complementary internal locking groove 42 on the locking part 30.
[0053]The locking system 44 shown in FIG. 26 has a locking part 46 of the female type and a locking part 48 of the male type. The locking parts 46 and 48 are for example made of noble metal, for example gold or silver, why the locking parts 46, 48 are provided with inserts 50 and 52, of which the insert 50 is made of stainless steel with a locking groove 54 and a locking position with a locking hole 56, respectively, in which the insert 56 of stainless steel may engage with an external locking pin 58. The locking parts 46 and 48 furthermore have internal holding magnets 10 and 12 disposed in the inserts 50 and 52. Besides, the locking parts 50 and 52 have loose end parts 60 with relatively large connecting holes 62 for leather straps, of which loose ends may be fastened in the end parts 60 by means of locking pins inserted through transverse holes 64 of the end parts 60.
[0054]FIG. 27 shows a locking system 62 which, besides a locking part 64 of the female type and a locking part 66 of the male type, comprises an intermediate piece 68 which at opposite ends is provided with complementing locking parts so that the intermediate piece 68 may be fixed in a secure way between the locking parts 64 and 66. The intermediate piece 68 may, for example, be used to connect a separate part of jewelry to one or more pieces of jewelry, for example, in the form of necklaces, bracelets, ankle bands, headbands, belts or the like. As indicated, the intermediate piece 68 may possibly have several lesser intermediate pieces so that the length may be adjusted thereby.
[0055]FIG. 28 shows a locking system 70 where a spatial jewelry part 72 having two hingedly connected halves 74 in which is formed a mainly cylindric hollow 76 adapted for receiving a locking part 78 of the female type and a locking part 80 of the male type in such a way that the locking parts 78 and 80 may be fixed in the hollow 76 when the halves 74 are joined together. The jewelry part 72 is a magnetic material so that the holding magnets in the locking parts 78 and 80 also can hold the jewelry part 72 closed around the locking parts 78 and 80. If the jewelry part 72 is made of non-magnetic material, there may--as shown in FIG. 29--be provided an external lock 82 for holding the jewelry part 72 closed around the locking parts 78 and 80.
[0056]The locking system 84 shown in FIG. 30 includes a larger jewelry part 86 which at one side is fitted with a locking part 88 of the male type that interacts with a locking part 90 of the female type which is mounted at the end of a jewelry cord 92, which at the opposite end is provided with a locking part 94 of the male type interacting with a locking part 96 of the female type which is fitted in the jewelry part 86 diametrically opposite the locking part 88.
