ABSTRACT:
A pin locking device for preventing an involuntary unlocking of a pin which is bent back on itself to form a spring, the pin having a pointed end section and a clasp mechanism mutually adjacent each other, the clasp mechanism retaining the pointed end section in a clasped condition against the urging of the spring. The pin locking device includes an elongated lock member having a body of a finite length made of a non-compressible material and having first and second spaced and parallel holes extending transversely through the body. An axially outwardly opening slot is provided in one end face of the lock member and extends entirely across the end face parallel to and opens into the first one of the transversely extending holes. The pointed end section of the pin extends through the second hole. The first hole receives therein a part of the pin extending between the clasp mechanism and the spring through the axially outwardly opening slot to thereby prevent the pointed end section of the pin from being able to move toward the aforesaid part of the pin between the clasp mechanism and the spring in order to effect an unclasping of the pointed end section from the clasp member.
