Abstract

PURPOSE:To make it possible to connect a synsetic resin pipe to a body to be connected, simply and surely by providing screw shaped engaging projections and also providing a truncate cone like part with the smooth outside surface on the tip of the part to be connected. CONSTITUTION:On the inner periphery of a cylindrical sleeve 40 inserted around the tip of a synsetic resin pipe 20, there is screw engaging projections 45 screwed around the outer periphery of the synsetic resin pipe 20 and also there is provided a truncated cone like part 15 with a smooth outside surface on the tip of a coupling 10 as a part to be connected. Thus, a sleeve 40 and the synsetic resin pipe 20 are holded with a hand and the tip of the synsetic resin pipe 20 is screwed in the sleeve 40, so that a cap nut 30 engaged with the sleeve 40 is screwed to a male thread part 11 of the coupling 10. This causes the tip of the synsetic resin pipe 20 to be extended by the truncated cone like part 15 so as to form a flare. Therefore, without a special purpose tool, it is possible to connect the coupling to the synsetic resin pipe, simply and surely.

(Effects of the Invention) As described above in detail, in the present invention as set forth in claim 1, the synthetic resin pipe can be screwed and fixed into the sleeve by hand or with a general-purpose tool, and furthermore, the screwed synthetic resin pipe can be fixed to the sleeve. Since the locking protrusion is spiral, it will not come out of the sleeve even if a tensile force is applied. Therefore, when a cap nut is screwed into the male threaded part of the object to be connected, the tip of the synthetic resin pipe is pushed out from the inner side by the outer surface of the truncated conical part, and a flare is formed there. Synthetic resin pipes can be easily and reliably connected to objects to be connected such as joints and branch pipes without using large and expensive special tools.
