As others have said, the type of strap that works with that type of clasp needs to be thinned to a maximum of about 3mm thickness along the length where the holes are. Most straps are too thick to fit this type of clasp, and most of the straps that do are spec'd specifically to work with it. In comparison, the generic butterfly or single fold clasps will work with almost any strap.
