ABSTRACT:
Line holding apparatus including a tubular mounting member secured in a substantially stationary position to a support, a cap which fits against the end of the mounting member spaced outwardly from the support, and a spring yieldably biasing the cap against the end of the mounting member. An elongate arm secured to the cap extends upwardly therefrom to confine and hold a portion of a cable when the cap is held against the mounting member. A lip on the cap engages side surfaces of the mounting member to inhibit lateral shifting of the cap. A member attached to the cap engages a notch on the end of the tube to inhibit rotation of the cap and arm. A force applied by the line against the arm which is greater than the biasing force of the spring releases the arm in almost any direction in which the line force is applied. An adjustment device is provided for increasing or decreasing the tension force of the spring.
