Abstract

A locking ring (30) is provided for assisting axial insertion and snap fit of an actuating head (5), including a pump (7), to a medium reservoir base (6) while protecting the pump (7) against actuation or excessive forces encountered during assembly. The locking ring (30) can be disengaged to allow actuation of the pump (7) and then re-engaged to permit actuation.
