The short answer is "no", but I have found dozens of kilt pins on the field at highland games where the tin pin has bowed and pulled out of the clasp, allowing the pin to fall off the kilt.

By the way, to prevent the loss of a "proper" kilt pin, one should always make sure that the clasp faces the hem, not the waist, of the kilt.
