Abstract

A rope ( 1 ) according to the invention comprises a main rope segment ( 4 ), a branching position ( 5 ) and an end connector segment ( 6 ), wherein the end connector segment comprises a first rope-branch ( 11 ) and a second rope-branch ( 12 ). The first rope-branch ( 11 ) comprises a noosed first rope-branch portion ( 21 N) for making a noosed connection with a thickened rope portion, or a thickened first rope-branch portion for making a noosed connection with a noosed rope portion. The second rope-branch ( 12 ) comprises a noosed second rope-branch portion for making a noosed connection with a thickened rope portion, or a thickened second rope-branch portion ( 22 T) for making a noosed connection with a noosed rope portion. The rope according to the invention allows for many various favourable manners of connecting the rope to other ropes and/or to other types of external objects.

and wherein the thickened second rope-branch portion of the rope and the noosed rope portion of the further rope are configured for making a noosed connection with one another.

18. Use of the assembly according to claim 17 , wherein:

a noosed connection is made between the noosed first rope-branch portion of the rope and the thickened rope portion of the further rope; and/or

a noosed connection is made between the thickened second rope-branch portion of the rope and the noosed rope portion of the further rope.

19. The rope according to claim 1 , wherein the rope is obtained from a first rope, which comprises said noosed first rope-branch portion, and a second rope, which comprises said thickened first rope-branch portion,

by splicing an end portion of a first main rope segment of the first rope into an intermediate portion of a second main rope segment of the second rope, or

by splicing an end portion of a second main rope segment of the second rope into an intermediate portion of a first main rope segment of the first rope.

20. A method of manufacturing a rope, wherein the method comprises manufacturing a main rope segment and an end connector segment,
