A magnetic clasp for an article of jewelry is provided. The clasp includes a pair of mating male and female members, an alignment groove on one member, and associated alignment projection on the other member and a safety catch. The pair of mating male and female members are arranged to be magnetically coupled to each other. The safety catch is arranged to be moved to a locked position to mechanically releasably secure the male and female members together when they are aligned. The alignment groove is shaped to facilitate and guide the projection into it when the two members are magnetically coupled and appropriately aligned so that the safety catch can be moved to the closed position to thereby releasably lock the members together.

What is claimed is: 1. A magnetic clasp for an article of jewelry comprising a pair of mating male and female members arranged to be magnetically coupled to each other along a common longitudinal axis, a safety catch arranged to be moved to a locked position to mechanically releasably secure said male and female members together when said members are aligned, and alignment means for facilitating the alignment of said male and female members so that said safety catch can be moved to said locked position, said alignment means comprising a recess in one of said male and female members and a projection in the other of said mating male and female members, said projection being complimentary shaped and arranged to be located within said recess when said mating male and female member are aligned to prevent twisting of either of said male and female members with respect to each other about said common longitudinal axis before said safety catch is moved to said locked position. 2. The magnetic clasp of claim 1 wherein the recess is shaped to guide the projection into it. 3. The magnetic clasp of claim 1 wherein said safety catch comprises a hook element pivotably connected to said one of said male and female members and a cooperating catch element connected to said other of said male and female members, said hook element being arranged to be pivoted to engage said catch element to effect the releasable locking of said male and female members together. 4. The magnetic clasp of claim 1 wherein each of said male and female members are each of a general barrel shape having a hollow interior, and wherein at least one of said male and female members includes a magnet located within said hollow interior. 5. The magnetic clasp of claim 2 wherein the recess is generally V-shaped. 6. The magnetic clasp of claim 2 wherein said safety catch comprises a hook element pivotably connected to said one of said male and female members and a cooperating catch element connected to said other of said male and female members, said hook element being arranged to be pivoted to engage said catch element to effect the releasable locking of said male and female members together. 7. The magnetic clasp of claim 3 wherein said projection comprises a portion of said safety catch. 8. The magnetic clasp of claim 6 wherein said projection comprises a portion of said safety catch. 9. The magnetic clasp of claim 7 wherein said hook element is mounted on said male member and said catch element is mounted on said female member. 10. The magnetic clasp of claim 8 wherein said hook element is mounted on said male member and said catch element is mounted on said female member.
