A flexible tubular device composed of a plurality of movably interconnected tubular elements is provided, particularly for use as a protective tube for a flexible endoscope. At least two first extensions are provided at one end of each tubular element. Each of the extensions engages into a corresponding recess of an adjacent tubular element. The ends of the first extensions are bifurcated for locking the first extensions in the recesses.
