-14- Abstract of the Disclosure: An improved cable following apparatus especially suitable for use in replacing an existing underground cable is dis- closed herein. This apparatus utilizes a telescopically configured main body disposed around a cable in question and front and rear cable gripping mechanisms which alternatively grip the cable so as to cause the telescopic body to slide along the latter in a forward direction. The cable follow- ing apparatus also includes a technique for releasing both of the gripping mechanisms from the cable at the same time in order to be able to pull the entire apparatus rearwardly in the event it becomes necessary or desirable to do so.
