ABSTRACT:
An object of the present invention is to provide a pipe joint device, according to which two pipe members can be easily connected and disassembled without causing the abrupt discharge of the fluid from the pipe members. A ring shaped first retaining member is mounted on a second pipe member and comprises; a ring portion; multiple leg portions axially extending from the ring portion and circumferentially arranged at equal intervals; and multiple first retaining portions formed at each free end of the leg portions and projecting radially and inwardly, so that the first retaining portions are inserted into apertures of the second pipe member. The above first retaining portions return to the initial shape after a first pipe member has been completely inserted into the second pipe member, so that the first pipe member is axially retained by the first retaining portions at an outwardly expanded portion of the first pipe member.
