Abstract

A device and method for retaining a line on a drum is disclosed. The drum has a slot which extends from a point along the periphery and into the drum in a first direction and at an acute angle relative to a tangent at the point. A clamp is provided with a slot portion and a line retaining portion. The slot portion is engaged with the slot such that relative movement between the clamp and the drum causes the slot portion to move in the first direction. As tension is applied to the line, a first force is created on the slot member in the first direction, resulting in a second force being applied by the line retaining portion in the first direction, clamping the portion of the line against the drum.
