Abstract: A connection device for pulling an aircraft. The connection device includes first and second connection portions, a connection rod and a rod retaining portion. The first and second connection portions have first and second guide spaces into which the connection arm is inserted. First and second arm receiving portions are pushed to rotate from a standby state by the connection arm inserted into the first or second guide space, and are connected by a link member. When the first arm receiving portion rotates from the standby state, the rod retaining portion rotates together with the first arm receiving portions, and enables the connection rod to pass through the second hole so that the connection rod is connected to the connection arm inserted into the first guide space or the second guide space.
