During the flare; the yoke clip which was extended impacted the [seat belt] quick release knob and stopped any [further] back stick [motion]. This occurred at about three feet. I had just broken the sink rate and the nose was transiting too slightly above the horizon when the yoke clip impacted; I believe; just above the quick release knob and stopped into the metal tabs from the shoulder straps. I briefly thought of going around; but since I couldn't rotate; I ruled that out. Being in an -800; I was concerned now about trying to pull harder and having the yoke break free with an excessive nose up input and possibly having a tail strike. The pitch attitude was fine; but I knew I would get a firm landing; which happened; followed by a small bounce or skip. This all took place in about two seconds. Roll out was normal. Normally I always close the yoke clip to the flat position before landing and additionally my seat may have been a little more forward than normal. Note or caution in the AOM in the landing section. Recommend the yoke clip be in the down or flat position for landing. I know most of the yoke clips you can't even get to stay up.
B737-800 Captain reports his extended yoke clip contacting his seat belt quick disconnect during flare; restricting further travel and causing a firm landing.
