Abstract
A fastener for jewelry has a bottom body having a stud forming a male part, a safety disc movable relative to the bottom body between an open position in which it leaves a space between the stud and the safety disc and a closed position in which the space is not provided, a spring urging the safety disc to the closed position so that for displacing the safety disc from the closed position to the open position the safety disc has to be displaced against a force of the spring, and a female member connectable with the article of jewelry and placeable on the stud in the open position so that in the closed position the female member cannot be withdrawn from the stud.

A fastener for jewelry, comprising a bottom body having a stud forming a male part;
- a safety disc movable relative to said bottom body between an open position in which a space is between said stud and said safety disc and a closed position in which said space is not provided;
- spring means urging said safety disc to said closed position so that for displacing said safety disc from said closed position to said open position said safety disc has to be displaced against a force of said spring means;
- a female member placeable on said stud in said open position so that in said closed position said female member cannot be withdrawn from said stud;
- a guiding shaft on which said safety disc is moveable in said open and said closed positions;
- and a support formed as a projection extending from a surface of said safety disc which faces said closing body and arranged so that said guiding shaft extends through said projection of said safety disc and is guided in said projection of said safety disc so as to guide said safety disc during its movement between said open and said closed positions.
