Abstract
A jewelry clasp having a pair of housings at the free ends of a piece of jewelry and are affixed together by magnetic forces. Each housing has a permanent magnet located therein and which magnets are attracted to each other when the housings are brought together. There is a safety catch on one of the housings having a protuberance extending therefrom that enters a slot in the other body. The slot passes entirely through the housing so that the protuberance can enter the slot in a first orientation and in a second orientation where one housing is inverted 180 degrees from the first orientation. The safety catch also includes a nib that aligns with an indentation formed in the slot and the entering of the nib into the indentation can be felt and/or heard by the wearer to provide assurance that the safety catch is in its locked position.
