A connection pin handling device has first and second sleeves mounted on a common axis and having corresponding first and second inlets disposed respectively at first and second opposite sides of the device, each inlet alignable with a selected connection pin on the corresponding side of the device. First and second push rods are slidably mounted for movement along the common axis in the first and second sleeves, respectively, to engage, by a selected one of the first and second push rods, a selected, aligned connection pin disposed at the respective, corresponding side of the connection pin handling device. A spring is disposed between the first and second push rods and exerts an insertion force on the selected push rod which applies a force to, and moves, the selected connection pin engaged thereby for performing an insertion or an extraction operation thereon.
