The invention relates to a separating link (20; 30; 40; 50) for an energy chain (10) made of chain links which have two side link plates (11) that are connected together by two transverse webs (12) atleast in the case of some chain links. The separating link (20; 30; 40; 50) has at least one elongated recess (22), which is designed as a through-hole for a transverse base (18), in the central part(21B; 31B; 51B) of the separating link, said recess opening into a narrow side of the separating link via an insertion opening (24; 34; 44; 54) such that a transverse base can be inserted through theinsertion opening (24; 34; 44; 54). According to the invention, the separating link (20; 30; 40; 50) has a respective bending region (23; 43; 53) for each recess (22), the gap width of the insertionopening (24; 34; 44: 54) of the corresponding recess (22) being modifiable by means of the bend of said bending region. In this manner, the gap width of the insertion opening (24; 34; 44; 54) can be reduced to a width (C1) which is small in comparison to the clear width (W) of the recess (22), in particular in the assembled state of the separating link, whereby, among others, an inserted transverse base is secured.
