Abstract
A circular discoid member is secured in a cylindrical member by means of a resilient split ring received in an annular groove formed in the internal surface of the cylindrical member. The resilient ring projects radially inwardly into engagement with an abutment zone of a peripheral surface of the circular member to retain the circular member against a biasing force applied thereto in one axial direction, while permitting displacement of the circular member in the other axial direction. A peripheral surface portion of the circular member on the opposite side of the resilient ring to the abutment zone has a diameter less than the internal diameter of the resilient ring when received in the groove and at least equal to the internal diameter of the ring when compressed for introduction into the cylindrical member. The circular member is displaceable relative to the cylindrical member in the said other axial direction by an amount enabling the resilient ring to be retracted radially out of the groove of the cylindrical member.
