Abstract
A pipe assembly includes male and female joints. The female joint includes a rotary coupling member rotatable around an outer peripheral surface of a female joint body, and a locking member pivotable relative to the rotary coupling member. The rotary coupling member has a surface facing a rear end portion thereof. A male joint body is configured to be inserted into the rotary coupling member such that rotation of the rotary coupling member to a coupling position causes a projection to engage the surface, and the male and female joint bodies to be sealingly engaged in a coupled state. The locking member is configured to be pivoted to a lock position in the coupled state wherein the locking member interferes with the projection, thus inhibiting the rotary coupling member from rotating from the coupling position to an uncoupling position where the surface is out of engagement with the projection.
