Cable tie

A cable tie having a flat strip made of plastic with two opposite edges, comprising:

• a head integrally formed on a rear end of the flat strip having a flat pull-through opening for inserting and pulling through a front section of the flat strip, the head having a metal strip that is inclined into the plane of the flat strip and having a V-shaped cut with two edges and a width greater than the width of the front section of the flat strip;
• an interior cross-section of the pull through opening roughly corresponding to a cross-section of the front section of the flat strip;
• and
• an end point of the flat strip in a pull-through direction having two opposite edges with comers;
• wherein:
• when the front section of the flat strip is pulled through the metal strip in the head, the metal strip forms an acute angle with the flat strip that points in the pull-through direction, and the two opposite edges with comers of the flat strip cooperate with the two edges of the V-shaped cut in the inclined metal strip to oppose a backward movement by the flat strip.
