A line tensioning device (4) comprising a body (44), a line guide member (42) rotatably mounted to the body (44) and having means to seat and guide a line as it changes direction. The line tensioning device also comprises a spring (46) disposed to bias the line guide member (42) in one rotational direction whereby to tension the line and ratchet means (48, 50) coupling the line guide member (42) and the body (44). The ratchet means (48, 50) includes an engagement member (48) responsive to a very slow change in the operating rotational position of said line guide member (42) in one rotational direction, over multiple cyclic movements of the line, to move from one ratchet position to a next ratchet position. |
