A lightweight plastic cervical collar includes a one-piece injected molded body, of a flexibility and length sufficient to enable the body to be wrapped around the neck of a wearer. One or more absorbent compressible foam strips are attached to an inner side of the body. A front section of the body defining part of a front collar half includes a generally T-shape integrally molded chin support. Upper edge portions of the body are made flexible by the provision of elongated openings and integral hinges formed by molded grooves extending generally longitudinally in the body. A first fabric-strip fastener is adhered to the front body section near one free end while a second, matably configured flexible fabric-strip is extended from the free end of the rear body section to join the adjoining collar ends together. Where the molded body extends around a tracheal opening, transverse reinforcement ridges are molded in the body to prevent collapse. A resiliently flexible, generally T-shaped joint at the upper center of the front section of the molded body provides firm yet resilient upward support of the wearer's head while preventing forward or lateral movements of the jaw. Slots are provided along the upper and lower edges of the rear body section to assist in wrapping the collar around the wearer's neck. A series of central openings are also provided in the rear collar half for air circulation.
