The elongated body defines longitudinally extending inserting channels extending from one end to an intermediate portion. Once inserted into pipes, the two pieces are urged apart by a screw to lock the fitting in the pipes. A second two-piece fitting may be attached via its engagement with an inserting channel. The second fitting has a portion insertable into a pipe and may be clamped within the pipes and to the first fitting by a screw urging apart the two pieces of the second fitting.
