Abstract
A ring member includes a split body having a split part split at a point in the circumferential direction and also includes a tapping screw that connects a first thin-walled portion and a second thin-walled portion forming the split part, which extend in the circumferential direction, in a state where the first thin-walled portion and the second thin-walled portion overlap one another in the radial direction of a first pipe. With the first thin-walled portion located on the radially inner side of the first pipe being fitted in an annular groove formed in the outer circumference of the spigot, the body can come into contact with a lock ring located inside a socket of a second pipe. The body has, on the second thin-walled portion, an engaging portion that is engaged with the first thin-walled portion in the axial direction of the pipes.
