The parking brake lever and heat lever knob are exactly the same; one above the other.  In-flight; the parking brake was pulled instead of the heat lever. Upon landing roll-out and actuation of brake pedals; the parking brake engaged and locked the wheels. The plane skidded in a wheel landing down the runway; as energy decreased the plane slowly rotated forward on the main gear striking the prop on the grass runway and eventually nosing over onto the cowl/nose. The leading edge outer pilots side wingtip bow also hit the ground. Corrective actions include changing the parking brake knob to a T handle or something that is identified by touch as being different; disabling the parking brake; or adding 'check parking brake off' to pre-landing checklist as it is not part of the approved checklist.
GA pilot reported pulling the incorrect lever inflight resulting in locking the wheel on landing and had a prop strike.
