A laryngeal blade assembly includes a light pipe assembly attached to a blade having a light pipe disposed along a major dimension of the blade. The light pipe assembly is releasably attached to the blade in a non-axial direction in relation to the major dimension, wherein said light pipe assembly can be released from the blade without the aid of tools. The light pipe assembly includes a supporting block for fixedly retaining the light pipe. The supporting block has a bore disposed in a non-axial direction to the major dimension of the blade. A non-axial member fixedly attached to the blade and sized for engaging the bore includes an undercut portion. An annular engagement member is fitted within said undercut portion for engaging the bore to allow the release of the light pipe assembly when a predetermined holding force is exceeded.
