Abstract: A cap having an opening mounted on the upper end of a damper includes an annular wall which encircles the cap opening and projects upwardly from an upper surface of the cap. A plurality of resilient tabs extends radially from the upper end surface of the annular wall. The lateral dimension of the tabs is slightly greater than an opening in support structure of a vehicle, e.g. a mounting tower. To quickly connect the upper end of the damper to the mounting tower, the mounted end cap is forced through the tower opening to compress the tabs. As the tabs clear the tower opening, each tab springs radially outwardly to retain the damper in place.
