Abstract
A T-block fitting (22) has an integral molded plastic body (24) including a stem (28) with a radial shoulder (26) and a radial flange (30) on opposite ends. An externally threaded split nut (40, 42) has a major portion (40) with a circumferential extent greater than 180.degree., and a minor portion (42). Complementary chordal mating surfaces (46, 62) are formed on the major and minor portions (40, 42). A semicylindrical projection (64) extends perpendicularly from each mating surface (62) and is received into a corresponding recess (48) in the abutting mating surface (46). A slot (50) extends along each mating surface (46) on the head portion (54) of the major portion (40). The slot (50) opens onto an outer surface of the head portion (54) and terminates in an inner enlarged diameter portion (52). A corresponding projection (66) with an enlarged inner end (68) is formed on each mating surface (62 ). The nut portions (40, 42) are made from a material which is sufficiently resilient to permit the major portion (40) to be snapped onto a tubular member and the major and minor portions (40, 42) to be snapped together.
