Abstract
A tracheostomy device having an inner cannula with a connector head and an outer cannula. The inner cannula is secured within the outer cannula by a locking device having spaced apart, elongated handles that are pivotally mounted on the inner cannula. The handles are spaced such that a connector may be mounted on the connector head, thereby preventing movement of the handles. A method of locking the inner cannula to the outer cannula is also described.
