Need Help Finding Holster Clip/Strap

[aaron2310]

I have a vest similar to this: http://cgi.ebay.co.uk/New-CQB-Tactical-Vest-Holster-Belt-Black-Airsoft-/160492628749?pt=UK_SportingGoods_OtherSports&hash=item255e1b2b0d

 

Unfortunately the clip and strap that would attach to the holster has disappeared. I know this'll sound like a stupid question but does anyone have any idea where I could buy a replacement online?It's a press stud. Here's my holster:

 

 

Thanks in advanced.

 

EDIT: Or thinking of it, just buy a new holster and use the strap from that? Doh! Please delete.
