The original Bosch dishwasher drain hose to house drain connector failed. It is a rubber piece about 3 inches in length that snapped over the end of the drain hose and then clamped over a 3/4 inch copper house drain line. I can't find a replacement part (Bosch doesn't list one), so what is used to connect Bosh's drain hose (P/N AP2802212) to the house drain? I bought the above part thinking that it would come with the appropriate connector, but it didn't. None of the "hardware store" variety of connectors have a large enough inside diameter to accept the nearly 1 inch dia. drain hose and the drain hose looks to be too fragile for a clamp-on type of fitting.
