ABSTRACT:
A safety clutch for an earring has a body member provided with a through hole arranged for receiving a post of an earring or other article to be releasably attached to the body member. Provided on the body member is a suitable resilient biasing arrangement disposed for normally engaging with the post of the earring and holding the post secure with respect to the body member. The retainer includes a clutch pin slidably disposed in a recess provided in the body member and arranged communicating with the hole so as to cause the clutch pin to selectively come into retaining engagement with a groove provided in the post of the associated earring. A coiled helical spring or other suitable biasing device is disposed in the bottom of the recess, beneath the clutch pin, for forcing the pin toward a position in which the pin engagingly holds the post in place in the hole provided in the body member.
