The collar provides an opening sized to closely fit the outlet through the majority of its peripheral extent and which provides peripherally spaced enlarged portions adapted to clear the projections on the connector when the bag is installed and removed. The collar also provides an inwardly extending elastomeric diaphragm having a centrally located opening substantially smaller than the outlet of the connector. During installation and removal of the bag on the connector, the enlarged portions of the collar opening are aligned with the projections on the connector and the collar is pressed over the connector until it is positioned behind the projections. The collar is then rotated to a mounted or installed position in which it engages the rearward sides of the projections to secure the two members together. The elastomeric diaphragm tig…
