Abstract: An anchor device includes a connecting member between an anchor and its anchor line, having a first part designed to be fastened to one end of the shank of the anchor and a second part extending axially and designed to be fastened releasably to the first part and to be connected to the anchor line; including a piston which is slidable in a cavity of the second part; and a body designed to be moved by sliding along the anchor line until it interacts with the piston, thus releasing the first part and second part.
