Method and apparatus for sealing connections between electrical power cords

A method for sealing an electrical connection, the method comprising:

• providing a flexible, substantially water-impermeable sleeve having two diametrically opposed creases running along the length of the sleeve, and having an opening at both ends of the sleeve, each opening having a thin strip of adhesive around its inside edge such that a portion of the interior of the sleeve remains free of adhesive;
• sliding the sleeve over a first electrical power cord having a connection end;
• connecting the connection end of the first electrical power cord to a connection end of a second electrical power cord thereby forming an electrical power cord connection;
• positioning the sleeve relative to the electrical power cord connection such that said connection is located within the sleeve;
• and
• pressing the edge of each sleeve opening against itself such that each opening is sealed closed, thereby sealing said connection inside the sleeve.
