A protective sheath for cable includes a series of casings. Each casing has a first end and a second end. Each casing includes a recess defined in the first end and having an inner diameter which is equal to or greater than an outer diameter of the second end. A groove is defined in the recess. A passageway is axially defined in each casing. A washer is disposed in the groove and has a through hole defined therein for communicating with the passageway. A cable passes through the through hole of each washer to be gripped and protected by each washer.
