ABSTRACT:
A pipe joint clamp for connecting piping members includes a circular holding portion in which flange portions of the piping members are clamped, and multiple flexion-shaped hinge portions, which protrude from the holding portion toward a diametrically outer side thereof. The hinge portions are resiliently deformable to accommodate a variation of outer diameters of the flange portions. Thus, a protrusion amount of the each hinge portion can be reduced. Accordingly, the space occupied by the clamp at the joint part of the piping members is decreased.
