Abstract
A medical device tube having extended retention tabs with notches therein for improved coupling of an inner cannula connector to an outer cannula connector. The medical device tube comprises an outer cannula connector having retention tabs on an outer cannula connector flange attached to the proximal end of an outer cannula. The retention tabs maintain the snap ears of the inner cannula connector when the inner cannula connector is rotated whereby the notches substantially hold the snap ears. The snap ears may further be positioned in notches in the outer cannula flange when the snap ears lock onto the outer cannula connector flange.
