Abstract
A loading unit and retention clip assembly include a shell and a resilient retention clip. The shell has a proximal end portion and includes an annular surface that defines engagement openings. The retention clip is disposed about the annular surface of the proximal end portion. The retention clip has ends and a body between the ends. The retention clip has a lug positioned adjacent to each end of the body that extends inward from the body. Each lug is configured to extend through the engagement openings of the proximal end portion of the shell to releasably couple the shell to a surgical instrument.
