5. The surgical access attachment according to claim 1 , wherein the ring includes a distal wall and an intermediate wall, the intermediate wall interconnecting the proximal wall and the distal wall.
6. The surgical access attachment according to claim 1 , wherein the access portion assembly is configured to disengage from the ring in response to a predetermined amount of proximally-directed force exerted on the tab.
7. The surgical access attachment according to claim 1 , wherein the tab and the lip of the access portion assembly are configured to removably engage the ring.
8. The surgical access attachment according to claim 1 , wherein the proximal wall of the ring is configured to be positioned proximally of a proximal-most portion of the surgical access device.
9. The surgical access attachment according to claim 1 , wherein the tab extends from the proximal seal retaining portion.
10. The surgical access attachment according to claim 1 , wherein the tab extends from the proximal seal retaining portion and at least partially through an opening of the distal seal retaining portion.
11. The surgical access attachment according to claim 10 , wherein the opening of the distal seal retaining portion is defined by a C-shaped projection extending radially outward from an outer ring of the distal seal retaining portion.
12. The surgical access attachment according to claim 1 , wherein the proximal seal retaining portion includes a plurality of fingers and the distal seal retaining portion includes a plurality of engagement apertures, each finger of the plurality of fingers is configured to mechanically engage one engagement aperture of the plurality of engagement apertures.
13. The surgical access attachment according to claim 1 , wherein the access portion assembly is configured to engage the ring in a single-handed manner.
14. The surgical access attachment according to claim 13 , wherein the access portion assembly is configured to disengage the ring in a single-handed manner.
15. The surgical access attachment according to claim 1 , wherein the access portion assembly is configured to non-rotatably engage the ring in a single-handed manner.
16. The surgical access attachment according to claim 15 , wherein the access portion assembly is configured to non-rotatably disengage the ring in a single-handed manner.
