[Detailed Description of the Invention] [Field of Use and Outline of the Invention] The present invention relates to a fixture for a pipe terminal such as a gas cock, and in particular, a connection state between a pipe inserted through a wall surface and a terminal device such as a gas cock. When it is fixed to the terminal device, the connection posture between the terminal device and the pipe terminal is kept constant so that the terminal device can be attached accurately and easily.

[Prior Art and Problems Thereof] In recent years, gypsum board is often used for indoor wall surfaces, and in such wall surfaces, indoor piping is arranged so as to pass through a space formed in the wall surface. . Then, a pipe terminal of the pipe is projected from an opening formed in the gypsum board, and a terminal device such as a gas cock is fixed to this.

In the case of this method, there is an advantage that the indoor piping is buried in the wall surface, but since the strength of the gypsum board is insufficient, and because the flexible tube is adopted as the indoor piping, conventionally , A pipe terminal fixing tool (No. Shokai 63-145281) as shown in FIG. 9 is adopted.

This conventional one forms an opening (H) of a sufficient size in a plaster board constituting a wall surface (W), and a joint (20) is attached to the tip of a flexible tube (2) drawn from this opening (H). Through the gas cock (1)

The gas cock (1) and piping end are fixed to the wall surface (W).

In this conventional one, the gas cock (1) can be connected to the fitting (20) after the fitting (20) is once fixed to the wall surface (W) by the backing plate (4) and the mounting plate (6). The gas cock with the flange directly attached to the
Workability is improved as compared with the pipe terminal fixing structure in which (1) is fixed to the wall surface.

However, this conventional device has a problem that the mounting posture of the gas cock (1) cannot be accurately set.

Since this is a type in which the connecting cylinder of the gas cock (1) and the joint (20) are screwed together, the mounting posture of the gas cock (1) differs depending on the screwing degree of both, and the mounting plate (6 ) Is mounted on the wall (W) in a fixed posture, the gas cock (1)
This is because the mounting posture of is not constant.

The present invention is a flexible tube arranged in such a "wall surface (W).
(2) and the connection pipe (11) of the terminal device such as the gas cock (1) connected to the pipe terminal are connected via the joint (20), and are attached to the outer surface of the wall surface (W). Mounting plate (6) and wall (W)
