Abstract:
1. A strain relief device for protecting a power cord, comprising: a truncate tubular base member defining a lumen adapted to accommodate an elongate power cord; said lumen including a trailing lumen, a leading lumen, and an annular recess formed therein between said trailing and leading lumens; said leading lumen having flat, tapered sidewalls that converge toward one another in a leading-to-trailing direction so that a diameter of the leading lumen at a leading end is greater than a diameter of a trailing end of said leading lumen; a tapered cylindrical plug having a first end greater in diameter than a second end and having a protruding rim formed in said second end; said diameter of said protruding rim being substantially equal to the diameter of said annular recess; said plug and said base member being formed of elastomeric materials having sufficient flexibility to enable said plug to be inserted into the leading lumen of said base member until said rim snaps affirmatively into said annular recess; said plug being sized to fit snugly within said tapered leading lumen.
