ABSTRACT:
An improved joint assembly has a boot seal with a retainer ring. The retainer ring is effective to hold the seal in place on a housing having a circular side surface with any one diameter in a range of diameters. The retainer ring includes an annular base having a plurality of interspersed groups of radially inwardly extending fingers or tabs. Each group of fingers includes fingers of different lengths to cooperate with housing side surfaces having different diameters within the range of diameters. Thus, each group of fingers includes a medium length finger which cooperates with a housing side surface having a diameter that falls within a middle portion of the range of diameters. Each group of fingers also includes a relatively short finger which cooperates with a housing side surface having a diameter which is greater than the mid-range diameter. Similarly, each group of fingers includes a relatively long finger which cooperates with a housing side surface having a diameter which is smaller than the mid-range diameter.
