PROBLEM TO BE SOLVED: To provide a fixing pin for connection surely preventing the connection and coming- off of both members and also simplifying a release of coming-off preventive state. SOLUTION: A coming-off preventive mechanism 3 comprises a fixing plate body 4 freely traveling to the inside and outside of the fixing pin 1 for connection, and an urging member 5 retaining the fixing plate body 4 at a position outside the fixing pin for connection. The fixing plate body 4 comprises a pressure receiving portion 4a at one end portion, an operating portion 4b at other end portion, a shaft connecting portion 4c at a central pressure receiving portion side, and a fixing pawl portion 4d at a central operating portion side. When the fixing pin 1 for connection penetrates the both members 2 to be connected, the fixing pawl portion 4d is freely traveled to the inside and outside of the fixing pin for connection inside the both member 2, and the operating portion 4b is freely traveled to the inside and outside of the fixing pin for connection outside the both members 2. The fixing pawl portion 4d can be automatically moved to a position outside the fixing pin for connection by means of urging force from the pressure receiving portion 4a and can be also moved to a position inside the fixing pin for connection by means of pressed force from the operating portion 4b. In the fixing pin 1 for connection, the fixing plate body 4 is surely operated, and coming-off from both the members 2 is surely prevented at the fixing pawl portion 4d, and the coming-off preventive state is easily released in the operating portion 4b different from the fixing pawl portion 4d.
