Abstract
A strain relief device, especially for power tools, has a pin upon which is pivotally mounted a clamping member with a spirally curved rough clamping surface which coacts with a second clamping surface. An electrical line is inserted between these surfaces and the clamping member is swung thereby applying a clamping force to the electrical line. When strains are applied to the line, the clamping member provides an increased clamping force by swiveling so that a section of the member of larger diameter presses the line against the second clamping surface. A lock mechanism is also provided to prevent the electrical line from being pushed further into the housing.
