Abstract In a parted spacer expander for a piston oil control ring of the type which includes an array of alternating inner and outer crowns connected by gener- ally diverging spring legs and a support pad extending radially from each inner crown and connected thereto by a pad leg, an improved slip latch comprising a curved rod having a substantially D-shaped cross sec- tion and having a radius of curvature equal to or less than the free-state radius of curvature of the spacer- expander. One end of the latch extends through at least one leg opening formed between the spring legs and pads adjacent the expander-ends and is formed with a stop having an axial dimension which prevents passage through the leg openings. The other latch end extends over an arc of at least seventy-five degrees through a plurality of leg openings in the opposite expander end and is free to slide through the leg openings. The free latch end terminates in an inwardly directed bev- eled face to permit the free end to ride over the edges of the leg openings during sliding motion therethrough. -i-
