Abstract
A method of securing connections in well screens can include engaging a resilient ring with recesses formed in respective well screen connectors, the ring including projections extending from respective opposite ends of the ring, and disengaging the resilient ring from one of the recesses by relative displacement between the projections. A well screen connection can include well screen connectors, and a resilient ring received in annular recesses formed in the respective well screen connectors, projections extend from opposite ends of the ring and are received in an opening formed through a wall of one of the connectors, and the projections received in the opening prevent rotation of the ring relative to that connector.
