Abstract: An accessory for enclosing the connection area between low voltage power cables has a pair of rigid end flanges for disposition over the adjacent insulated portions of the cables with an elastic wrap around corrugated elastomeric flap intermediate portion between the end flanges for tightly enwrapping the cable connection area. The cables are passed through housing parts or ports in the end flanges, the connections are made, and the wrap around flap is tightly drawn about the connection, making a sealing union with the flanges. Longitudinal edges of the flap are joined and clamped together.
