ABSTRACT:
A chain coupling device comprising a ring member adapted to be coupled to a hoisting mechanism, and a chain coupling mechanism adapted to be coupled to at least two hoisting chains (101, 201). The chain coupling mechanism comprises a unitary anchoring body (1) being made in one piece and being securable to the ring member. The unitary anchoring body has at least two pairs (6a, 6b; 7a, 7b) of anchoring projections, each pair of anchoring projections being provided with a detachable anchoring pin (6d, 7d) for anchoring an end link (102, 202) of an associated hoisting chain (101, 201) to the unitary anchoring body. The unitary anchoring body also has at least one pair (10a, 10b; 11a, 11b) of coupling projections being located at a distance from a corresponding pair of anchoring projections and being provided with seating surfaces for accommodating one (204) of the links of the associated hoisting chain.
