Description

technical field

[0001] The present invention relates to an in-line pipe joint capable of reliably connecting a pipe to a joint with simple operations. Background technique

[0002] The work of connecting pipes such as water pipes and wiring pipes arranged in each room of the house to the joints is numerous depending on the scale of the building and the number of rooms, so it needs to be done quickly and reliably. As an invention of a joint corresponding to such a request, there is an in-line pipe joint disclosed in Patent Document 1, for example. The structure of this conventional invention is that when connecting the pipe body (pipe) and the joint body, the female thread formed on the cover (gap) member is screwed into the male thread formed on the joint body, and the inner circumference of the coil spring-shaped ring A lock ring or the like forming a restricting piece is fixed on the surface. Then, the tube body is inserted into the joint main body from the cover member,...
