The present invention provides a cable protection device and a cable having the same. The cable protection device is configured for connecting two cables and includes a first protective casing and a second protective casing assembled with the first protective casing. The first protective casing has a hollow body for allowing one of the two cables to be disposed through. The second protective casing has a hollow body for allowing the other of the two cables to be disposed through. The interiors of the hollow body of the first protective casing and the hollow body of the second protective casing form a protective space respectively for covering a connecting portion of the two cables. Thus, the present invention also generates waterproof and dustproof effects.
