for the wires 965 to be securely connected to the contacts of jack 40 if the wire organizer 950 has not been inserted deeply enough into the body 960 of jack 40 the interior wall 900 and the lever 880 prevent complete closing of the tool 700 the tool 700 is in the embodiment shown in fig8 a to be brought from its open position into its closed position manually an operator a technician or the like is required to insert wires 965 into the wire organizer 950 insert the body 960 of a jack 40 into the tool 700 while the tool 700 is in its open position manually insert the wire organizer 950 partly into body 960 of jack 40 and manually pivot the actuators 800 and 800 u2032 towards each other simultaneously thus bringing the tool 700 into its closed position and thereby inserting the wire organizer 950 into the body 960 of jack 40 whereby the wires 965 are securely connected to respective contacts in the jack 40 in order to facilitate the pivoting of the actuator 800 and thus the closing of the tool 700 the actuator 800 is equipped with a grip element 910 located close to the end of the actuator 800 which is opposite to its hinged end the grip element 910 is an essentially plate like flat element connected with the bottom wall 870 or forming one part with it and.
