## Abstract

An apparatus and method for sealing an electrical connection, such as a connection between two electrical power cords, thereby protecting the electrical connection from moisture or water intrusion. The electrical connection is surrounded by a flexible, substantially water-impermeable material, such as a plastic sheet. The sheet has strips of adhesive around its perimeter. The sheet is folded around the electrical connection such that adhesive on one portion of the sheet is joined to adhesive on another portion of the sheet to form a sealed volume that surrounds the electrical connection. The electrical connection also may be sealed within a plastic sleeve having adhesive strips along the inside edge of the opening at each end of the sleeve.

## Claims

### Claim 1

An apparatus for sealing an electrical connection, the apparatus comprising:
a flexible, substantially water-impermeable sleeve, having an opening at each of two ends and two diametrically opposed creases running along the length of the sleeve; and
a thin strip of adhesive along the inside edge of each opening such that a portion of the interior of the sleeve remains free of adhesive;
wherein the ends of the sleeve may be compressed such that the adhesive adheres to another portion of the sleeve or adhesive, and seals the sleeve around the electrical connection.

### Claim 2 (depends on 1)

The apparatus of claim 1, further comprising a removal backing for covering the adhesive until it is ready to be used.

### Claim 3 (depends on 1)

The apparatus of claim 1, wherein the sleeve is made from a flexible plastic material.

### Claim 4 (depends on 1)

The apparatus of claim 1, wherein the electrical connection comprises a connection between two electrical power cords.

### Claim 5

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.

### Claim 6 (depends on 5)

The method of claim 5, wherein the step of pressing the edge of each opening against itself further comprises, for each opening, pressing the adhesive strip portion between the two creases on one side of the opening, against the adhesive strip portion between the two creases on the opposite side of the opening.

### Claim 7 (depends on 5)

The method of claim 5, wherein the strip of adhesive is covered by a protective backing, and the method further comprises removing the backing before the openings are sealed closed.

### Claim 8 (depends on 5)

The method of claim 5, wherein the sleeve is made from a flexible plastic material.
