Claim Text:
1. 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 two opposed longitudinal limb sections of the first limb; a threaded bore defined in the first limb, the threaded bore running in a longitudinal direction of the first limb and extending into the two opposed longitudinal limb sections of the first limb; a closure screw disposed in the threaded bores that, in a screwed-in state, engages in the threaded bore in the two opposed longitudinal limb sections of the first limb, wherein an external circumference and a link width of the main body are of a predefined size, such that, while retaining the predefined size for the external circumference and link width of the main body, the link width is provided with a larger profile cross section in an area of the longitudinal limbs than a profile cross section in an area of the curved link portions, wherein the threaded bore defined on a first of the two opposed longitudinal limb sections on which the closure screw is inserted into the threaded bore is provided continuous from the receiving opening up to the area of the curved link portion, while the threaded bore in a second of the two opposed longitudinal limb sections, starting from the receiving opening, defines a blind hole over a predefined longitudinal area.
