A cable connector assembly is disclosed for use in connecting electronic devices together. The connector has a housing and a mating blade in the form of a paddle card to which wires of a cable are terminated. The connector housing supports a latching mechanism with an actuator that when selectively pulled delatches the latching mechanism from its engagement with the housing of an electronic device. The actuator has an elongated pull tab portion that has a rounded edge for at least three of its four sides. This rounded edge eliminates the sharp corners associated with rectangular or square cross sections of conventional pull tabs, thereby removing stress riser points and giving the pull tab greater resistance against tearing when subjected to torsional loading.
