Abstract

A universal joint construction comprises a plastic housing casing portion which includes an interior cavity forming a ball receiving socket which has an opening in a wall bounding the opening exteriorally of the socket which is bevelled outwardly to an end from the socket. The exterior of the wall is bevelled outwardly in a direction toward the socket. The exterior of the housing casing has an annular groove around the socket which is adjacent to the wall. A ring portion is advantageously formed integral with and connected to the casing by a connecting web of slight thickness. The ring portion has a bore with a radially inwardly extending collar of a diameter to engage over the bevelled wall and be advanced over the bevelled portion of the wall to cause the inward deflection of the wall so as to permit the collar to move beyond the bevelled wall and engage in the groove.
