## Abstract

The device, which is intended to connect a shackle (1) to the links (2) of a chain using a bolt (8), comprises two parts (3) and (4), part 3 being a cylindrical body that guides the insertion/extraction of the bolt (8). A lever (7), which is joined to the bolt (8), extends from the side of the cylindrical body (5) and can be displaced in order to move the bolt (8). Part 4 comprises a nut (9) screwed to the end of the bolt (8) in order to secure such bolt (8). The invention also includes a handle (10) that can be attached to the nut (9) to allow the bolt (8) to be tightened by a robot. Parts 3 and 4 include brackets (11) and (12) between which through-rods (13) are screw-mounted at the ends thereof in order to secure said parts (3) and (4) to one another.

## Claims

### Claim 1

A shackle connecting device, for use in the connecting of a shackle, which includes a bridge, to a chain of links,
wherein a joint between the shackle (1) and a link (2) of the chain is via a cross bolt (8), and comprises
first and second parts (3, 4) related to each other in a mountable and removable manner,
wherein the first part (3) constitutes a guiding part for guiding the bolt (8),
wherein said bolt (8) is arranged for coupling between the link (2) of the chain and the bridge (1) of the shackle,
wherein the second part (4) constitutes a mooring part arranged to moor the bolt (8),
wherein the first part (3) is constituted by a cylindrical and hollow body (5), with a longitudinal side slot (6),
wherein a lever (7) is fixed to the bolt (8), emerges from the longitudinal side slot (6), and is movable.

### Claim 2 (depends on 1)

The shackle connecting device, according to claim 1, wherein the second part (4), comprises a nut (9) threaded on the end of the bolt (8).

### Claim 3 (depends on 1)

The shackle connecting device, according to claim 1, wherein the second part (4) and the cylindrical body (5) of the first part (3), have brackets (12, 11) with holes for passage of rods (13), said rods (13) having nuts for fixing the first and second parts (3, 4) to each other.

### Claim 4 (depends on 2)

The shackle connecting device, according to claim 2, wherein the second part (4) and the cylindrical body (5) of the first part (3), have brackets (12, 11) with holes for the passage of rods (13), said rods (13) having nuts for fixing the first and second parts (3, 4) to each other.
