Abstract
In a chain lock with essentially U-shaped lock parts (,), each lock part has an inner limb (,) and an outer limb (,) which are connected to each other by a yoke. The outer and inner limbs (,) are connected to each other in a closed position of the lock by three pairs of holding teeth (,). For increasing the strength of the lock, the holding teeth (,) of the central pairs of holding teeth, and the holding teeth (,) of the pairs of holding teeth arranged in the region of the ends of the inner limbs (,), have a greater height (H) than the holding teeth (,) of the other pairs of holding teeth. All holding teeth (,) support each other only over a central supporting zone which is limited in its height.
