ABSTRACT OF THE DISCLOSURE A split ring spring for snap fasteners has a burr extending from each end of the ring spring in a direction parallel to the imaginary central axis of the ring spring. When a stud member is snapped with a socket member in which the split ring spring is incorporated, the burrs do not damage or scar a body of the stud member. The ring spring having such unobjectionable burrs is produced by feeding a length of a strip of resilient material transversely across a mandrel, then severing the length off the strip in a direction parallel to the longitudinal axis of the mandrel while holding the length on the mandrel, and thereafter bending the severed length of strip around the mandrel.
