Energy chain having a skid, and skid retrofittable therefor

An energy chain to guide at least one line between two connection points, of which at least one of the connection points is movable relative to the other, comprising:

• a plurality of links connected in a longitudinal direction, which are pivotable relative to each other and each have two side plates and cross bars connecting the side plates to each other, wherein in a case of a relative movement of the connection points, the energy chain is movable, forming two runs, which merge over a deflection area,
• wherein one run is slidable on the other run and, for the sliding, in each case a pair of skids are arranged on an inner side in the deflection area and on links of at least one longitudinal section, wherein both skids of a pair are fastened in each case to a cross bar by a holding device and in each case reach over a narrow side of one of the two side plates in an operative position,
• wherein at both of its ends, at least the cross bar provided with skids has in each case a widening towards the side plate, and
• wherein the holding device has two opposing holding elements, which are spaced apart in the longitudinal direction and with which the holding device is fittable onto the cross bar between the widenings and is displaceable laterally outwards into an engagement with one of the widenings, in which engagement the opposing holding elements engage in a positive-locking and/or force-locking manner in or behind an area of this widening to fasten the skid in the operative position.
