• a cable receiving groove Is provided on a surface of said press member which is opposed to said contact section, said cable receiving groove comprising:
• a guiding section which faces said contract section when said press member is at said open position;
• a retention section which faces said contact section when said press member is at said closed position;
• and
• a transition section provided between said guiding and rotation sections and having a width which gradually decreases from said guiding section to said retention section, wherein said cable is easily inserted into said cable receiving groove through said guiding section and being supported by said transition suction and said retention section while said pressing member is rotated from said open position to said close position, thus firmly press-fitting said cable to said teeth of said contact section of said contact element.
