The collar (14) has a deformable sleeve (29) that is oversized relative to a portion of the tracheostomy tube (11) which extends therethrough. In an undeflected condition, portions (46,46) of the sleeve (29) engage the tracheostomy tube portions (43) to fix its height. When the sleeve (29) is deflected by compressing the sleeve (29) together at selected points, the engaging sleeve portions (46,46) will be deflected away from the tracheostomy tube portions (43) to permit axial movement thereof. | |
