PURPOSE: A chain link and energy-conveying chain with lockable cross beam are provided, in which a transverse portion which can connect the chain side plates is pivotable both about the one chain side plate and also about the other, wherein latchability of the transverse portion to a chain side plate at least at one side is to be possible. CONSTITUTION: A chain link comprises two opposite link plates (2) which are at a mutual spacing, and at least one cross beam (5). The cross beam (5) comprises at both ends a detachable hinge (10) which can be connected to the link plate (2). The cross beam (5) can be locked to the link plate (2). In order to lock the cross beam (5) to the link plate (2), the hinge (10) comprises a hinge pin (7) and a recess which co-operates with the latter and has undercuts. The hinge pin (7) comprises a locking projection (9) which engages in a cut-out extending over part of the periphery of the recess.
