Abstract: A connector for joining the ends of two pipes has a pair of half-sleeves, which fit around the pipe ends to form an inner sleeve. The inner sleeve has a tapered or conical outer surface, against which an outer sleeve presses. The outer sleeve is a single-piece sleeve with a tapered bore, the angle of the taper of which matches the angle of taper of the outer surface of the inner sleeve. The outer sleeve is slid over the inner sleeve and is clamped in intimate contact with the inner sleeve by a nut which is tightened onto a threaded end of the outer sleeve while an annular, inwardly - projecting flange of the nut bears against the ends of the half-sleeves. The surfaces of the half-sleeves are coated with adhesive before being placed around the pipe ends; this adhesive cures while the joint components are clamped together. Preferably each half-sleeve has a central rib at its mid-point, against which the ends of the pipes being joined abut.
