Chain joint for link chains

Chain joint for link chains, comprising:

• a main body in the form of an oval chain link having two longitudinal limbs that are parallel to each other, the longitudinal limbs being connected together at respective adjacent ends thereof via curved link portions, wherein a first limb of the two longitudinal limbs defines a receiving opening for hooking oval chain links into an internal opening defined by the main body, the receiving opening being delimited by a longitudinal limb section;
• a threaded bore defined in the first limb, the threaded bore running in a longitudinal direction of the first limb and extending into both longitudinal limb sections, the threaded bores being configured to receive, a closure screw that, in the screwed-in state, engages in the threaded bore in both longitudinal limb sections,
• wherein a size of the external circumference and a link width of the main body are predefined, such that, while retaining the predefined sizes for external circumference and link width of the main body, the link width is provided with a larger profile cross section in the area of the longitudinal limbs than a profile cross section in the area of the curved link portions.
