Abstract: The invention provides a ball-and-socket joint comprising two joint components one of which is constituted by a ball having a convex spherical surface integrally connected to a supporting rod, while the other joint component is constituted by a socket having a concave spherical surface partially surrounding said ball and frictionally connected thereto, wherein at least one of said components comprises a plurality of elements each of which defines a spherical surface section complementary to the spherical surface of the other joint component, said elements being pressed in substantially radial directions with their respective spherical surface sections, by biasing means, against the spherical surface of the other joint component.
