To provide a cable end-jointing structure that can prevent a connection stopper from being directly caught to the other parts, effectively avoid the damage of the connection stopper and can simply unfasten the connection with the connection stopper.

This joining structure comprises the terminal part 2 set to the cable 1 and the joining part 3. In the terminal part 2, the connection stopper 4 and the protector 41 that is equal to or larger than the connection stopper 4 in their sizes are radially protruded at a prescribed gap 40. Further, guiding grooves 24 are formed on both sides in the same direction as that of the connection stopper and the joining part 3 has incision 33 joining to the guide groove 24 and the part 34 intervening into the gap 40 and the protrusion 44 formed on the connection stopper 4 and the top edge 35 of the intervening part 34 are detachably connected.
