The invention relates to a connector for detachable connection to an article to enable a cord, chain or the like to be attached to the article. There is disclosed a connector attached to a ball to provide a captive ball for playing games. The connector has a generally elongated body portion and is split longitudinally into two halves from one end to a position part the way along the connector. The one end is enlarged with respect to the body portion immediately adjacent thereto and a screw is adapted to cause expansion of the enlarged head in a direction transverse to the longitudinal axis of the connector when the head of the screw is pulled between the two halves by a cylindrical nut arranged on the screw in a cut-out in the body. The cut-out prevents longitudinal movement of the nut. Expansion of the end enables it to be retained in any suitable cavity accessible through a restricted neck portion. The other end of the connector has an enclosed loop for receiving a cord, chain or the like. The connector may be used to attach pendant jewelry to a neck chain or hang ornaments from a ceiling or other structure as well as for many other purposes. A further form of the connector having a cylindrical body for insertion into an article is also disclosed.
