1. A chain link for an energy guide chain for guiding lines between two connection points that are movable relative to one another, having a line-protecting internal subdivision, the chain link comprising two mutually spaced-apart side plates which are connected to one another by two crossbars and which delimit an interior space open in a longitudinal direction for guiding lines, and which in each case have inner surfaces facing toward the interior space, wherein:
a frame module is mounted between the two crossbars, wherein the frame module substantially frames a sub-region of the interior space and, for the purposes of internal subdivision, delimits at least one guide space in cross section perpendicular to the longitudinal direction; and
the frame module comprises two side walls and two transverse regions running transverse thereto, wherein each transverse region in each case covers a part of the inner surface of a crossbar and forms a line-protecting bearing surface for the purposes of line-protecting internal subdivision, wherein the transverse regions are in each case formed in one piece with at least one of the side walls.
