A bite block for an endotrachial tube includes a hollow body extending between open ends to receive an endotrachial tube such that opposing ends of the tube protrude through the open ends of the bite block. The bite block includes a tether to retain the bite block to the tube to prevent unwanted separation or movement of the tube within the bite block. The tether consists of a flexible arm which protrudes rearwardly from the bite block towards the inlet end of the tube and terminates in a ring configured to encircle the endotrachial tube, thereby effectively tethering the bite block to the tube. The arm and ring are configured such that the arm flexes in an arc when tethering the tube, thereby permitting the ring to engage the tube when fitted to thereto.
