EMT compression slide over coupling three piece assembly

A compression coupler assembly comprising:

• a first compression nut;
• a second compression nut threadably attached to the first compression nut;
• and
• an inner sleeve configured to be captured between the first compression nut and the second compression nut when threaded together, the inner sleeve including:
• a tubular-shaped body having opposite ends,
• a plurality of fingers at the opposite ends of the tubular-shaped body, wherein each of the plurality of fingers is configured to deflect inwardly as the first and second compression nuts are threaded together;
• and
• at least one tab protruding radially inwardly from an inner wall of the inner sleeve, wherein the at least one tab is integrally formed with the wall of the inner sleeve and disposed in an opening formed through the wall of the inner sleeve, the tab being configured to be resiliently deflectable radially outwardly.
