Abstract
To mount a partition cover (2) in a pipe joint (1), a nut (12) is screwed onto a joint body (11) to sandwich the partition cover (2) between the joint body and the nut. At this time, the partition cover is supported so as not to press a sleeve (13). As such, an opening (1a) of the pipe joint is sealed while preventing the sleeve from being deformed due to the partition cover being mounted.

A pipe joint for connecting a pipe, the pipe joint comprising:
- a joint body through which a joint hole to be connected with a pipe is formed,
- a fastener member to be fastened to the joint body,
- a sleeve that is caused to bite into in an outer periphery of the pipe by the fastener member being fastened to the joint body with the pipe having been inserted into the joint hole, and
- a partition cover constructed to be removable from the pipe joint, wherein, when the pipe is not connected to the pipe joint, the partition cover seals an opening of the pipe joint, and when the pipe is connected to the pipe joint, the partition cover is removed from the pipe joint,
- wherein, when the pipe is not connected to the pipe joint, the fastener member fastened to the joint body allows the partition cover to be sandwiched between the joint body and the fastener member, and the partition cover is mounted on the pipe joint to define a space between the partition cover and the fastener member, a length of the space being configured to be greater than a length of the sleeve in an insertion direction of the pipe.
