In a positioning device, first and second members are mounted for movement (e.g. rotation) relative to each other. At least one of the members (e.g. of plastic material) has at least one through slot defining an elastically deformable strip integral with its body portion. In a first embodiment deformable strips flank the sides of a polygonal opening or pivot on one of the members in engagement with a circular pivot or opening in the other member. |
