A drag chain comprising a plurality of chain links connected to one another in an articulated manner for guiding cables between two connection points, wherein opposing link plates and crosspieces of the chain links form a receiving space for the at least one cable, wherein the drag chain can be arranged and moved as a structure formed by a lower track, an upper track and a deflection region connecting same, with the upper track being placed on the lower track, and wherein the chain links of the lower track and/or the upper track are or can be fitted with additional elements, e.g. sliding elements, on the side facing the respective other track. The chain has an end-securing part with connection-securing means for securing the end-securing part to a connection point or said chain is secured to a stationary connection point by means of same. At least one wedge-shaped ramp-type element is provided on the end-securing part of the lower track, on the side facing the upper track, said ramp-type element comprising a pointed end and a broad end spaced apart from one another in the longitudinal direction of the chain. The wedge-shaped ramp-type element is or can be arranged on the end-securing part with its longitudinal direction at least substantially parallel to the longitudinal direction of the chain, wherein, in the secured arrangement on the chain, the ramp-type element tapers in the direction leading away from the deflection region and the upper side of the ramp-type element facing the upper track forms a ramp-type surface for the upper track.

A drag chain for guiding cables between two connection points, wherein the chain has a plurality of chain links connected to one another in an articulated manner and succeeding each other in the longitudinal direction of the chain, wherein the chain links each have mutually opposite plates which are spaced apart laterally from one another and each have an inner and an outer side surface and each have two narrow sides which are opposite one another with respect to the plate height, wherein at least some or all of the chain links have at least one crosspiece which connects the plates of the respective chain link to one another, wherein the mutually opposite link plates and the crosspieces form a receiving space for the at least one cable, wherein the drag chain can be arranged and moved by forming a lower track, an upper track and a deflection region connecting the latter, with the upper track being placed on the lower track, wherein the chain links of the lower track and/or upper track are or can be fitted with additional elements, such as sliding elements, on the side facing the respective other track, the chain having an end-securing part which is coupled to an end link of the lower track of the chain and which has connection-securing means for securing the end-securing part to a connection point or said chain is secured to a stationary connection point by means of the same, wherein the end-securing part of the lower track has, on the side facing the upper track, at least one wedge-shaped ramp-type element with a pointed end and a broad end, which are spaced apart from one another in the longitudinal direction of the chain, in that the wedge-shaped ramp-type element is arranged or can be arranged on the end-securing part with its longitudinal direction at least substantially parallel to the longitudinal direction of the chain, wherein, in the secured arrangement on the chain, the ramp-type element tapers in the direction leading away from the deflection region and the upper side of the ramp-type element facing the upper track forms a ramp-type surface for the upper track.
