A coupling link (100) to be interconnected between a hoisting device and a shortenable hoisting chain (54, 55, 56). The coupling link is elongated and comprises a connecting portion (110) in the form of a loop for connection to the hoisting device and an anchoring portion (150) for anchoring of an end link (51) of the hoisting chain. A selected link, namely a support link (55), of the hoisting chain is inserted in a support slot (132) between two support shanks (131a, 131b) of the coupling link, and a hoisting chain link adjoining the support link, namely an engagement link (54), will make contact, at an end portion thereof, with corresponding seating surfaces (133a, 133b). The loop portion (110) defines a free internal space (111), which is dimensioned to enable pulling through the hoisting chain (50) for adjustment of its effective length and which directly adjoins the support slot (132).

Manille (100) reliant un engin de levage à une chaîne de levage (54, 55, 56) raccourcissable. La manille, allongée, comporte une partie (110) en forme de boucle se raccordant à l'engin de levage et une partie (150) s'engageant dans le maillon extrême de la chaîne de levage. L'un des maillons de la chaîne (le maillon d'accrochage) ayant été sélectionné est inséré dans une fente support (132) entre les deux bras porteurs (131a, 131b) de la manille tandis que le maillon contigu au maillon d'accrochage (54) de la chaîne s'appuie par l'une de ses extrémités sur les surfaces d'appui correspondantes. La boucle (110) délimite un espace libre intérieur (111) dimensionné pour permettre de tirer sur la chaîne (50) pour régler sa longueur efficace et qui touche directement la fente porteuse (132).
