Abstract
A tracheostoma prosthesis having inner and outer cannulas is provided with a lockable connection for releasably locking the inner cannula to the outer cannula under the influence only of compressive force for locking and tensile force for unlocking. Surfaces on a proximal part of the inner cannula for gripping by a thumb and forefinger are exposed by recesses provided in a proximal part of the outer cannula. These surfaces permit manual application of sufficient compressive and tensile force to respectively lock and unlock the lockable connection.
