A device for threading a line with, or through, an annular member, or other endless or apertured member, from a remote position, comprises a body for location at the end of a pole, a rotor having a recess therein, and a threading member to which a line is connected. The rotor comprises a pair of spaced discs having arcuate recesses on their facing surfaces which engage corresponding arcuate flanges on the body and threading member to allow the rotor to rotate with respect thereto. The rotor is biassed to maintain the recess therein open to a space between a threading portion of the threading member and a confronting portion of the body to receive a ring or other similar element in which the threading portion is engaged. On further movement, the rotor rotates relative to the threading member to allow the ring to pass onto a line attached to the threading member. |
