A device for securing a skin tube to a bendable tube portion that is formed at the distal end of the insert part of an endoscope, the bendable tube portion being bendable by remote control. The method of securing a skin tube to a bendable tube portion comprises the steps of: fitting a flexible skin tube over the bendable tube portion; fitting a fitting member into the groove at at least one end portion of the skin tube, the fitting member having a shape which is fittable to the groove; loosely fitting a securing device around the end portion of the skin tube, the securing device being formed from a shape memory material which has previously memorized a shape with which the securing device is capable of peripherally pressing the end portion of the skin tube and, at the same time, pressing the fitting member against the surface of the groove; and restoring the securing device to the memorized shape.
