A ball-and-socket joint is protected in sealed state by a boot firmly secured at its outer end to the ball stud of the ball and at its inner end to the joint assembly by a clamping ring made of an elastic material in the form of a coil wound spirally with rectangular-section winding turns thereof lying adjacently side-by-side in the plane of the clamping ring. The spirally-coiled construction, in contrast to a helically-coiled construction, of the clamping ring permits it to be expanded greatly at the time of its fitting in the boot groove for assembly with little permanent deformation, whereby a great clamping force is obtainable.
