ABSTRACT OF THE DISCLOSURE FASTENING DEVICE A fastening device comprises a base portion and a key portion, the base portion having a socket opening therein with a radial shoulder. At least an axial portion of the socket opening is in the form of a regular polyhedron, preferably 12 or 16 sided. The key portion has a furcated post, axial portions thereof being generally conformed to at least portions of the polyhedral socket. The post has a radial shoulder which snaps behind the shoulder of the socket to retain the key in position. As the key is rotated the post interferes in a periodic manner with the socket wall, thereby precluding the key from being accidentally turned. The device may suitably be molded from a resilient thermoplastic resin. The device may also comprise an eye within which the key is received, the eye comprising opposed washer like members the one having serrated posts upstanding therefrom, the other openings for receiving the posts therein in locked relationship.
