A device for connecting a chain or line, such as a portion of a chain or line, to a structure, the device comprising: a first portion comprising a first axis, the first portion being configured to connect or be connectable to a structure so as to be movable relative to the structure; a second portion comprising a first end region, which is proximal to the first portion, and a second end region, which is distal from the first portion, the second portion being configured to connect or be connectable to the first portion so as to be movable relative to the first portion; a wheel-shaped first guide element separate from the first portion, the first guide element being arranged on or relative to the first portion to be movable around or about the first axis of the first portion; a second guide element arranged on the first end region of the second portion and/or on the first portion, the second guide element comprising a passage for passing or threading a chain, the second guide element being arranged in proximity to the first guide element and configured to align at least a portion of a chain relative to the first guide element, the passage comprising or defining a cross-section adapted or configured to substantially match or correspond to at least part of a cross-section of a chain; and a chain engaging arrangement comprising a third guide element, wherein the device further comprises: a further passage for receiving at least a portion of a chain or line, the further passage being part of the second portion, a second axis, the second axis being part of the second portion and being arranged to be substantially perpendicular to the first axis when the first and second portions are connected to each other, and wherein the second guide element is configured to substantially align a longitudinal axis of at least a portion of a chain or line with a tangential portion of the first guide element. a first portion comprising a first axis, the first portion being configured to connect or be connectable to a structure so as to be movable relative to the structure; a second portion comprising a first end region, which is proximal to the first portion, and a second end region, which is distal from the first portion, the second portion being configured to connect or be connectable to the first portion so as to be movable relative to the first portion; a wheel-shaped first guide element separate from the first portion, the first guide element being arranged on or relative to the first portion to be movable around or about the first axis of the first portion; a second guide element arranged on the first end region of the second portion and/or on the first portion, the second guide element comprising a passage for passing or threading a chain, the second guide element being arranged in proximity to the first guide element and configured to align at least a portion of a chain relative to the first guide element, the passage comprising or defining a cross-section adapted or configured to substantially match or correspond to at least part of a cross-section of a chain; and a chain engaging arrangement comprising a third guide element, wherein the device further comprises: a further passage for receiving at least a portion of a chain or line, the further passage being part of the second portion, a second axis, the second axis being part of the second portion and being arranged to be substantially perpendicular to the first axis when the first and second portions are connected to each other, and wherein the second guide element is configured to substantially align a longitudinal axis of at least a portion of a chain or line with a tangential portion of the first guide element. a further passage for receiving at least a portion of a chain or line, the further passage being part of the second portion, a second axis, the second axis being part of the second portion and being arranged to be substantially perpendicular to the first axis when the first and second portions are connected to each other, and wherein the second guide element is configured to substantially align a longitudinal axis of at least a portion of a chain or line with a tangential portion of the first guide element.
