Abstract
A security clutch for a jewelry post includes a housing defining a post receiving aperture extending therethrough and an access port. A trigger lock member is disposed in said housing and includes a main body with an aperture therethrough defining a central post locking notch. A biasing member is connected to one end of the main body and a trigger portion is connected to opposing end to extend through the access port in the housing for manipulation from outside said housing. When the trigger is depressed against the biasing force of the biasing member, the main body is moved from a resting locked position to an unlocked position with the post locking notch being clear of the post receiving aperture, thereby permitting free passage of a jewelry post within the post receiving aperture. As a result, the security clutch can be easily and quickly installed and removed from a jewelry post when desired.
