Description of the Related Art Conventionally, as a pipe connecting tool, as shown in FIG. 3, a connecting tool main body 33 and a connecting pipe 31 which are externally fitted to a connecting pipe 31 and attached to a pipe 32 opened on the surface of a structure are packed 34. And a lock member 35 for fixing it in the connector main body 33 via a connecting member main body 33, a fitting portion 36 to the pipe 32 is formed at the pipe side end portion of the connector main body 33, and a male member is formed on the outer peripheral surface of the non-pipe side end portion. A threaded portion 37 is formed, and a tip end portion of the male threaded portion 37 is used as an abutting portion of the packing 34, and a packing accommodating portion 38 that opens to an end surface is formed on the inner peripheral surface of the lock member 35 on the pipe side. A female screw portion that is screwed into the male screw portion 37 of the connector main body 33 is formed on the inner peripheral surface of the portion 38, and the lock member 35 is screwed into the connector main body 33. Packing 3
There has been one in which the connecting pipe 31 is fixed to the connector main body 33 by pressing 4 toward the connector main body 33 side and bulging toward the connecting pipe 31 side. A slip washer 39 is interposed between the lock member 35 and the packing 34 so that the lock member 35 can easily slide in the circumferential direction with respect to the packing 34.

を接続するのが困難であった。However, in the above-mentioned conventional pipe connector, the male threaded portion 37 is projected to the side opposite to the pipe of the connector body 33, and the packing 34 is brought into contact with the contact portion at the tip of the male threaded portion 37. Since the lock member 35 is screwed together, the distance L from the mounting portion 36 of the pipe connector to the tip of the lock member 35 is inevitably long, and the pipe connector cannot be made compact. For this reason, when a sufficient installation space cannot be secured in the unit bath or the like, the connecting pipe 31 is connected to the pipe 32 opened on the surface of the structure.
Was difficult to connect.

ねるという問題があった。Further, the connecting pipe 31 is provided by an outer fitting support piece 41 in which the cover 40 for covering the pipe connecting tool is bent inward of the cover.
When the external fitting support piece 41 is externally fitted and supported, the tip end portion of the external fitting support piece 41 comes into contact with the lock member 35 to determine the position in the pipe axis direction.
Since the distance K between the tip end surface of the lock member 35 and the facing inner surface 42 of the cover 40 facing the tip end surface is long, and moreover, the distance L from the mounting portion 36 of the pipe connector to the tip end of the lock member 35 is long, the cover is formed. There was a problem that 40 could not cover the entire pipe connector, and as shown in the figure, a gap S was formed between the cover 40 and the surface of the structure to expose the pipe connector and impair the appearance.
