Abstract
A strain relief device for protecting a power cord includes a tubular base member defining a lumen adapted to accommodate a power cord. The lumen includes a trailing lumen, a leading lumen, and an annular recess formed between the trailing and leading lumens. The leading lumen has flat, tapered sidewalls. A tapered cylindrical plug is sized to snugly fit within the leading lumen and has a protruding annular rim at its narrow end. The diameter of the protruding annular rim is about equal to the diameter of the annular recess so that the rim snaps into the recess when the plug is inserted into the leading lumen. The plug is disposed in encircling relation to the power cord prior to insertion of the plug. Pulling on the power cord increases the compression of the plug about the cord due to the common taper of the plug and the leading lumen.
