A heat shrinkable strain relief device protects electrical wires passing through an aperture in a partition and secures the wires to the partition. The strain relief includes a first heat shrunk tube overlying the wires and having a diameter that is no larger than the diameter of the aperture. A second heat shrunk tube overlying a portion of the first heat shrunk tube has an outer diameter greater than that of the aperture. The strain relief is located in the partition with only a length of first heat shrunk tube that extends outward from the second heat shrunk tube passing through the aperture. A third optional heat shrunk tube positioned on the first heat shrunk tube is spaced apart from the second tube by a distance approximately equal to the thickness of the partition. The strain relief device is formed by locating lenghts of heat shrinkable tubing in predetermined positions on the wires, and applying heat.
