Abstract

The invention relates to a holding clip (1) for a valve drive, for coupling an actuating lever (2) to a valve drive member (5) actuated thereby, in particular of a pump arrangement (3). The holding clip (1) comprises a holding section (1a) which engages over the actuating lever (2) on a side remote from the valve drive member, and an attachment section (1b) for attaching the holding clip to the valve drive member, wherein the holding clip is positionally secured in the valve drive by the action of the attachment section (1b) against the valve drive member. As a result, it is possible in an advantageous manner to simplify the holding geometry acting on the actuating lever and to reduce the mechanical loading thereof.
