Help - Need a small part for Shure e2c

[Record9]

I am not sure how, but I lost the "funnel" shaped sleeve holder for my older set of Shure e2c's. Shure does not have the part available - was hoping that the grand internet could come to my aid..
 
 
You can see in this image the part that I am missing.
