Abstract
A medical device tube having opposing support ears for improved coupling of an inner cannula to an outer cannula. The medical device tube comprises an outer cannula having opposing support ears on an outer cannula connector flange attached to a proximal end of the outer cannula. The opposing support ears maintain locking ears of the inner cannula in substantially one position. The opposing support ears substantially prevent the locking ears in contact with the outer cannula connector flange from slipping therefrom by, e.g., rotation, axial displacement, torsional shear, etc.
