A shell cover of a data cable connecting socket is provided to prevent the shell cover from deformation even when a plug is repeatedly inserted/ejected into/from the socket to maintain a stabilized connecting state. A shell cover of a data cable connecting socket includes an upwardly tilted portion(1) and a latch piece(2) formed on the top face of a body(10). A slot hole(3) is formed in the latch piece. An insertion guide groove(4) is formed at the center of the tilted portion and faces the outside of the body. The latch piece is downwardly bent toward the inside of the body according to a bending line(5) formed at the boundary of the latch piece and the body. The end of the latch piece is upwardly bent according to another bending line(6). A protrusion of a plug shell cover is inserted into the body according to the insertion guide groove without having interference and elastically latched and fixed into the slot hole of the latch piece.
