An apparatus for inserting an expander ring into an inner circumferential groove of a split piston ring includes a first magazine for storing a stack of piston rings; and a second magazine for storing a stack of expander rings. The second magazine has a discharge end and a longitudinal axis coinciding with a longitudinal axis of the expander ring stack. There are further provided a device for displacing a piston ring from the first magazine into axial alignment with the longitudinal axis of the second magazine at the discharge end thereof; a spreader device for radially outwardly spreading the piston ring positioned at the discharge end; and a pusher for pushing an expander ring from the second magazine parallel to the longitudinal axis into the piston ring spread-open by the spreader device.
