Connecting device for securing two beams to each other, a method for using the connecting device, and tower including the connecting device

A connecting device (1) for securing two beams (28;

• 30) to each other end to end, wherein the connecting device comprises a pin (2), a shaft (4), and at least one splice element (6) provided with a first through hole (8) for receiving the shaft (4), and a second through hole (10) spaced apart from the first through hole (8) for receiving the pin (2), wherein there is a gap (14) between the pin (2) and the splice element (6) when the pin (2) is inserted in the second through hole (10), the shaft (4) is rotatable with respect to splice element (6) about a rotational axis (A) when the shaft is inserted in the first through hole (8), the connecting device comprises an eccentric ring (16) arranged in the first through hole (8) so that the eccentric ring (16) is rotatable with respect to the first through hole (8), the eccentric ring (16) has an opening (18) for receiving the shaft (4), the opening (18) in the eccentric ring is designed so that the eccentric ring (16) is rotated upon rotation of the shaft (4) when the shaft is inserted into the opening, and the centre (C1) of the eccentric ring is offset (O) from the rotational axis (A) of the shaft so that the splice element (6) is moved with respect to the pin (2) upon rotation of the shaft (4) and by that closes the gap (14) on one side of the pin.
