Magnum H.O.T. need part

Does anyone have an H.O.T. filter they were going to toss
and would like to give up the "Cover Lock"? That's the
piece of plastic on the top of the cover that grabs the
stiff wire and holds the cover on. I lost mine! And it's
not listed in the Marineland Magnum manual parts section.

I'm in the Portland Oregon area. Getting back into
fish/discus and finding out I have less old equipment than
I thought I had!
