A joint comprising: two members, a plurality of apertures formed in each of said two members, and two pairs of resilient rods positioned opposite to each other and interconnecting said two members, each end of each rod of said two pairs of rods being pivotably mounted in an aperture defined in a different one of said two members, one rod of each of said two pairs of rods having both its ends extending through said apertures in a direction opposite to the direction of extension through said apertures of both ends of the other rod of the same pair of rods, and each rod of each of said two pairs of rods being mounted to cross the other rod of the same pair of rods in frictional engagement, each member thereby being pivotably movable with respect to the other member and being held in a desired position by the frictional engagement of the two rods of each of said two pairs of rods.
