An energy guiding chain for guiding cables, flexible tubes or the like comprises a plurality of chain links (1, 2, 3) which are articulated to each other and which each include two lateral straps (1a, 1b, 2a, 2b, 3a, 3b) and upper and lower cross-members (4) connecting said lateral straps. For arranging the cross-members for easy pivoting on both lateral straps, while designing the lateral straps as slim as possible, and for guaranteeing smooth and correct sliding of the upper strand on the lower strand, it is provided that both the upper and lower cross-members (4) include on both ends thereof two cylindrical bearing parts (12) that can be inserted in pocket-like bearing receivers (13) arranged on the lateral strap which points towards the respective end of the cross-member, wherein said bearing receivers project on the sides of the lateral straps which point towards the interior of the chain, wherein the lateral straps include snap-action means having a snap tab that cooperates with a locking bar arranged on the respective end of the cross-member (4), and wherein the cross-members (4) on both ends thereof in the axial direction outside of the bearing parts (12) each include a projection extending in the longitudinal direction of the cross-member (4) and with a contact surface thereof resting against the side of a lateral strap pointing towards the interior of the chain, in the locking position of the cross-member. |
