NOTE: See photo #2. Shark also made a version of this with a plastic clip (see photo 2) instead of a screw to hold it in place. Both are interchangeable and compatible, you will receive the one with the screw (see photo 1). This is the spring-loaded latch that locks the elbow onto the body of the vacuum.
