Abstract

When releasing a connection between a second tube member and a first tube member, a ring member is moved, whereby an inclined surface of a bump part and an inclined surface of a bump part of a cam part slide, and a stopper rotates from a coupled position to an uncoupled position. Thus, a coupling between a leading end part of a claw part of the stopper on the second tube member, and a coupling surface of a coupling-accepting part on the first tube member is released. In connecting the first and second tube members, when the first tube member is pushed into the second tube member with the ring member in the locked position, the claw part of the stopper is elastically deformed, whereby the leading end part of the claw part rides past the coupling-accepting part, and couples to the coupling surface of the coupling-accepting part.
