ABSTRACT:
A tube connector includes an anchor body having a lengthwise through-passage and a bolt head cavity. The through-passage and bolt head cavity are open to a side of the anchor body. One end of the anchor body has a tool-access opening and the other end has a tapered portion. A bolt extends through the tapered end portion and has its head located in the bolt head cavity. The bold is inserted into the anchor body via the side opening. A tightening body has a lengthwise through-passage through which the bolt extends and a tapered end portion facing the tapered end portion of the anchor body. A nut engages upon the bolt, and an expansion body has a pair of opposed inward facing ramp surfaces, one of which bears against the tapered portion of the anchor body and the other of which bears against the tapered portion of the tightening body. Upon relative rotation between the bolt and nut the tightening body moves toward the anchor body to expand the expansion body against an internal surface of the tube end.
