Abstract: An actuation lever is provided that comprises a lever having a first end configured to engage and support a knob, a second end configured for connection to a lever-actuated device and a longitudinal axis. The mating knob includes at least one pocket having at least one inner peripheral surface. The first end of the lever includes a resiliently deflectable retaining member having a tine that includes a barb-like tip that engages the inner peripheral surface of the pocket. As the knob is inserted onto the first end of the lever, the tine deflects inwardly towards the longitudinal axis. The spring force generated by the deflected tine causes the retaining member to exert oppositely directed forces against the inner peripheral surface of the pocket. The barb-like tip on the end of the tine imbeds into an inner peripheral surface of the pocket to retain the knob on the first end of the lever.
