Positive lock pin

A positive lock pin for locking a plurality of objects together includes an upper housing in communication with a handle housing. The handle housing has a shaft member located therein. The shaft member is rotatable with respect to the handle housing and has a slot formed in an upper portion thereof. The shaft member also has a pair of recesses formed therein. The shaft member is in communication with a pair of retention mechanisms disposed within the handle housing. Each of the pair or retention mechanisms is in communication with a respective opening formed in the handle housing. The pair of retention mechanisms are moveable between a locked position where an outermost point thereof extends outwardly from a respective opening and an unlocked position wherein the outermost point does not extend outwardly from the respective opening and a respective retention mechanism rests in one of the recesses. The movement of the retention mechanisms occurs upon rotation of the slot and the shaft member.
