ABSTRACT:
An improvement in post-type earrings, which are earrings connected to a human ear by a rigid slender short rod or post. One end of the post is attached to an ornament. The post is rectilinear and cylindrical and extends from attachment to the ornament. In service, the other end of the post is pushed through an opening in a person's ear, and a suitable element is attached to the other end of the post to secure the earring on the ear. In the present invention, at least a portion of the outer surface of the post has a helical threading. The element used to secure the post on the ear is a clutch having a central opening about which are radially arrayed a plurality of spaced apart springy fingers. The fingers extend to terminal attachment to a base portion of the clutch. The clutch is engageable by the post by extending the post axially through the opening in the clutch, until the tips of the springy fingers pass over the convolutions of the threading and are held in the threading. The fingers cannot be moved reversely in an axial direction because in this direction they catch on the flanks of the threads. To disengage the clutch from the post, the clutch must be rotated about the post, so that in effect the clutch is pushed on axially and screwed off by rotary motion.
