Transverse bar and chain link with transverse bar

A side portion of a chain link for an energy guide chain having a holding portion for releasably fastening a transverse bar, comprising:

• the side portion having laterally spaced large-area side surfaces and upper and lower narrow sides which connect the side surfaces and which extend in a longitudinal direction of the chain,
• wherein the holding portion for the transverse bar has a recess which is open in a direction of a side surface for receiving a locking element of the transverse bar for lockingly fastening the transverse bar to the side portion to secure the transverse bar against a spacing from the side plate in a direction transversely relative to a longitudinal direction of the transverse bar,
• wherein the holding portion for the transverse bar is configured such that the transverse bar is loosely insertable into the holding portion from a direction perpendicularly to the narrow side of the side portion, extending in the longitudinal direction of the chain, in the region of which the holding portion is arranged, until reaching a transverse bar target position in which the transverse bar is lockable with the side portion with a locking element.
