A load-transfer device comprises a pair of rotary members each having an annular series of projecting peg-like elements, and a location member having arcuate tracks in its opposite sides to receive tip portions of the elements respectively. A wire or other elongate element extends beneath the location member and the upright parts of U-shaped clips supporting the wire are received in the spaces between the elements when the device encounters such clips, whereupon the members rotate relative to the location member to permit the clips to pass through the device.
