A connector comprising a body having a body central bore defining a body axis, with one end contoured to conform to the surface of the support member, and another end shape to coaxially abut the free end of the hollow member. Expansion means are carried by the body for close entry into the hollow member when the body and the free end about. Drive means pass through the body central bore and have one end adapted to engage the support member, and another end engaging the expansion means, to impart a radially outward force component to the expansion means as the drive means is drawn toward the support member. The expansion means can be in the form of resilient fingers cantilevered from the body into the hollow member, and the drive means can be a wedge member drawn by a bolt, toward the support member, for urging the resilient fingers outwardly. In an alternative configuration, the expansion means can be in the form of a metal clip having a plurality of transversely extending prongs, which are preferably arranged such that the cantilevered fingers pass between the prongs to maintain the prong orientation relative to the body axis. The drive means can, for example, be in the form of a threaded bolt which threadably engages and draws the clip toward the support member such that the prongs are urged outwardly into engagement with the hollow member. |
