A link such as a karabiner has a body portion and a gate portion which is mounted to the body portion about a pivot. The gate defines a free end which is arranged to inter-engage with a nose of the body portion to define a closed ring for receiving a rope passing therethrough and including a first sleeve which, when the ring is closed, is moveable between a first position where the gate is free to rotate about the pivot in at least one direction, and a second position where the sleeve at least partly encloses the free end of the gate and the nose and substantially prevents rotation of the gate about the pivot. The link further includes a second sleeve which is internally threaded and which is mounted on an externally threaded portion of the gate for movement towards and away from the free end of the gate and which may be rotated towards the first sleeve when the first sleeve is in the second position, to prevent movement of the sleeve into first position in which the gate is free to rotate. A dual sleeve maillon, of similar design but omitting the pivoting gate having two sleeves is also described.
A link which can be opened and closed, the link comprising a body portion and a first sleeve which is mounted on the body portion, and is movable from a first retracted position in which the link is open and a second position in which the first sleeve is inter-engaged with the body portion to define a closed ring for receiving an object, and further comprising a second sleeve which is internally threaded, and which is mounted on an externally threaded portion of the body portion for movement towards and away from the first sleeve and which may be rotated towards the first sleeve when the first sleeve is in the second position, and to prevent movement of the first sleeve into the first position in which the link is open, wherein the first sleeve is internally threaded and rotatably mounted on a further correspondingly externally threaded portion of the body portion, and wherein the pitch of the threaded portion on which the second sleeve rotates is different to the pitch of the further threaded portion on which the first sleeve rotates.
A karabiner comprising a body portion and a gate portion which is mounted to the body portion about a pivot, the gate portion defining a free end which is capable of inter-engaging with a nose of the body portion to define a closed ring for receiving an object, and comprising a first sleeve which, when the ring is closed, is moveable between a first position where the gate portion is free to rotate about the pivot in at least one direction, and a second position where the first sleeve at least partly encloses the free end of the gate portion and the nose and substantially prevents rotation of the gate portion about the pivot, and further including a second sleeve which is internally threaded, and which is mounted on an externally threaded portion of the gate portion for movement towards and away from the free end of the gate portion and which may be rotated towards the first sleeve when the first sleeve is in the second position, to prevent movement of the first sleeve into the first position in which the gate portion is free to rotate, wherein the first sleeve is internally threaded and rotatably mounted on a further correspondingly externally threaded portion of the body portion, and wherein the pitch of the threaded portion on which the second sleeve rotates is different to the pitch of the further threaded portion on which the first sleeve rotates.
