Abstract
A security clutch for a jewelry post, such as an earring post, is disclosed. The security clutch includes a housing with a top wall, a bottom wall and a side wall. An access port in the side wall and a post receiving aperture through the top wall and the bottom wall are also provided. A trigger is disposed within the housing and includes a button portion that protrudes from the housing and through the access port for manipulation by the user. A U-shaped post engaging member is disposed within the housing and is in communication with and lies in the same plane as the trigger. A spring-biasing member is connected to the U-shaped post engaging member to position the U-shaped post engaging member into partial blocking of the post receiving aperture and into engagement with the groove of a grooved post received therein. The button portion is depressed by the user, against the forces of the spring-biasing member to clear the U-shaped post engaging member from the post receiving aperture and from the groove of the grooved post to permit free movement of a jewelry post within the post receiving aperture.
