Just installed new plugs with the help of this DIY...thanks!

In the process I lost one of those little clips that hold the sensor wires on either side of the plastic cowling (can be seen in the following pic):



Does anyone know what the part number is for these? Stealership parts counter was clueless and I couldn't find anything on RealOEM:

Thanks!
