Abstract
Abstract An endoscope has an operating section and an insertion section. The insertion section includes a flexible tube and a bending tube. At least two wires for operating the bending tube from the operating section are each connected at one end to the bending tube, with at least two wire guides for guiding these wires being arranged in the flexible tube. The endoscope further includes a coupling member for coupling the flexible tube and the bending tube to each other. The coupling member consists of at least two parts which can be combined integral, and one of the wire guides is fixed to each of the parts.
