A computer connector with an automatic loop closure device, said device comprising two flexible metal sheets fixed by one of their ends to the printed circuit plate, so that they are operated by the opposed end by means of pins, which, adequately mounted on the support block, are displaced and press the free ends of the sheets as the cable end connector is coupled to the fixed connector, the device being opened in this case, while, when taking out the cable end connector, the sheets, due to their elasticity, recover their initial position, thereby producing the closure of the device which gives the loop continuity.
