The present invention provides a mechanism of retaining a rocker lever ball socket on a rocker lever ball. The mechanism provided is a retaining cap which is adapted to fit over and securely engage to the socket through a tab and groove arrangement and is made of a slightly elastic material and includes a restricted opening sized smaller than the fullest diameter of the rocker lever ball. During assembly, the retaining cap first interlocks with the socket by a tab and groove arrangement, and the lever ball is then pushed through the restricted opening. The restricted opening, being slightly elastic, enlarges to allow passage of the ball and retracts to a size smaller than the ball so that it is retained thereon.
