ABSTRACT:
A positive locking device for connecting an inner cannula within an outer cannula to form a tracheostomy tube device. The tracheostomy device is provided with a connector head or connector body having ribs and or lips with associated catches disposed thereon. Cantilevered members with latch receiving members corresponding to the catches are provided on the component (connector or connector head) not having the rib or lip. Alternatively, catches may be associated with cantilevered members and latch receiving members with lips or ribs. Catches and latch receiving surfaces interlock and a securing component is fixed over the connector and connector head to create a positive lock.
