摘要： A channel tube inspection device 1 includes an inspection head 3, a pushing cable 5 and an elongated intermediate part 7 whose one end 7a is connected to the inspection head and whose other end 7b is connected to the pushing cable. The intermediate part 7 has a radial rigidity or, worded differently, bending rigidity gradually increasing over its length. The bending rigidity of the intermediate part 7 gradually increases from the inspection head 3 to the pushing cable 6. The intermediate part 7 is solid and has a gradually diminishing diameter from the pushing cable 5 to the inspection head 3. The intermediate part 7 is made of plastic, preferably PUR.
