<p>A T-shaped structural joint connects a tubular member endwise to a plate member. The joint comprises a connector force-fitted in a hollow open end of the tubular member, the connector having on its periphery a knurled surface which is held in tight frictional engagement with the interior surface of the open end. The connector has an end face to which the plate member is screwed. The connector has a radially extending slot that allows the connector to contract when forcibly inserted into the tubular member, the connector having a tendency to expand or spring back under its own resiliency upon insertion such that the connector is forcibly pressed against the interior surface of the tubular member. The connector includes a split and tapered sleeve that facilitates initial insertion of the connector.</p> |
