Sporran belt makers have been using these piece of "crap" clasps for years. I have a dress sporran that I purchased nearly forty years ago that has what is call a lobster clasp that is correct. You can purchase a proper clasp at at least two craft stores. They are Michaels and JoAnns. I have several chain sporran belts and have replaced all of the clasps with the lobster type and have never had a problem.
