Abstract
The device is a swivel clip or swivel prong with a relatively rotatable swivel and base elements. The swivel element rotates about a shaft which passes through an aperture in the base element. The swivel clip is initially formed in one piece by molding windows in an upper portion of the swivel element which are opposed to molding windows in a lower portion of the swivel element (that is, alternating around the periphery of the shaft). The windows meet in the base member, forming the swivel shaft, the swivel aperture and the internal gates as a single piece. Subsequently breaking the internal gates provides vestiges which support the swivel shaft within the aperture. Radially oriented upwardly extending inverted V-shaped support boss formed on the swivel and base elements position the swivel and base elements with respect to each other.
