There are a few other clasps that are secure and some chains require a different method....
The Byzantine on the right has a fancy lobster with a catch chain for the bracelet.
The swing catch, ( below ), is also an option for bracelets.
Notice the capped ends on this Snake Chain
This large Curb has a passage catch and swing catch. It is just about impossible to 'unhook' on your wrist since it needs to be twisted, rotated and pulled to come loose.
