A hinge device of the present invention comprises a male hinge member, a female hinge member and a resilient tube. The male hinge member includes a connecting shaft at one end, a mounting plate at an opposite end and a shoulder between the connecting shaft and the mounting plate. The connecting shaft of the male hinge device forms a receptacle therein for receiving the resilient tube. Four channels are longitudinally defined in the connecting shaft and equiangularly distributed in the shape of a cross to prevent loss of friction in the hinge device. An arcuate surface is formed at each edge of the channels. The female hinge member includes a sleeve and a mounting plate extending from one end of the sleeve, the sleeve having a receiving opening for receiving the connecting shaft of the male hinge member. A longitudinal slot is defined through the resilient tube for enhancing resiliency and allowing expansion of the resilient tube.
