Abstract: Apparatus for removably attaching an item to a columnar member may include: a socket member for attachment to the item having a generally cylindrical interior terminating at a circular wall for receiving one end of the columnar member and a bushing member placeable over one end of the columnar member and receivable by the socket member to provide bearing and anti-galling surfaces between the socket member and the columnar member. A locking device may be carried by the socket member for engagement with the bushing member to apply radial forces to the bushing and columnar members to lock the item to the columnar member.
