A joint restraint is provided for a curved pipe joint having a curved pipe section joining two adjacent pipe sections. The pipes are joined using tubular sleeves held by hose clamps to form fluid tight seals, with two clamps on each end of the curved pipe sections and two clamps on each proximal end of the adjacent pipe sections. An inner strap extends between and fastens to one of the clamps on each adjacent pipe section forming a chord of an arc. An outer strap extends along an outer periphery of the joined pipes and fastens to the other clamps on each adjacent pipe section. The straps are in a plane through a center of the flow path of the joined pipes.
