The stoppers (30) are each provided with: an annular section (31) surrounding the outer peripheral surface (2A) of an inserted pipe (2); and a protrusion (32) protruding radially inward of the annular section (31) from the inner peripheral surface (31B) of the annular section (31). The protrusions (32) are configured to be elastically or plastically deformable, and have front ends protruding into the insertion space of the insertion hole (11), the insertion space being that into which the pipes (2) are inserted.
