ABSTRACT:
A pipe connector for connecting a pair of conventional, circular cross-section pipes whose axes are generally coplanar but are angled relative to each other, is formed of a pair of identical, but reversely arranged, tubular sections, each having an outer end for coupling to an adjacent pipe end and an inner end coupled to the adjacent section inner end. The coupling comprises conventional, releasable, circular pipe couplings which surround and clamp adjacent pipe ends together. The connector sections are bent and flattened in cross-section so that their inner ends are engaged in the plane of the pipe axes while their outer end openings are transverse to the pipe axes and overlap and open into the ends of the pipes. The portions of the connector sections between their opposite ends are of cross-sectional areas that are roughly the same as the cross-sectional areas of their end openings. Because the connector sections are flattened towards the plane of the pipe axes, the overall, outermost distance of the connector from the pipe axes is only slightly greater than the radius of the pipes themselves.
