The present invention discloses a device for connecting high voltage cables for forming one power transmission line by connecting conductors of the high voltage cables together and a joint box having the same. A device for connecting high voltage cables according to the present invention comprises a connection element, being comprised of first and second sleeves, each having a protrusion on a top thereof, for receiving first and second conductors, respectively, of first and second high voltage cables and fixing the first and second conductors with pressure; a contact bump, being coupled to the protrusion in a sliding manner and being ascended and descended through an assistant device; and an electrode unit, having a key hole that the contact bump selectively contacts with, where the first and second sleeves are coupled mutually thereto in a manner of male and female coupling. In a device for connecting high voltage cables and a joint box having the same, the first and second sleeves are coupled within the electrode unit in a manner of male and female coupling, under a condition that the conductors are independently coupled to the first sleeve and second sleeves so that a connection operation of the high voltage cables is simplified, convenience of work is enhanced, and the length of metal sheaths to be cut is minimized so that the length of the joint box is r educed and thus the manufacturing costs are decreased.
