Patent ID: 7322380

Claim:
A pipe insulation coupling for coupling adjacent ends of elongated pipe insulation tubing surrounding a tubular pipe comprising: an elongated body extending along a longitudinal axis between a first end and a second end, said elongated body including a first generally C-shaped clam shell portion and a second generally C-shaped clam shell portion; said first and second clam shell portions defining a cylindrical outer tube wall extending along said longitudinal axis between said first and second ends, a cylindrical inner tube wall spaced inwardly from and generally parallel to said outer tube wall and extending along said longitudinal axis between said first end and said second end, and a planar wall positioned transverse to said longitudinal axis for interconnecting said outer tube wall and said inner tube wall midway between said first and second ends and adapted to abut the adjacent ends of the pipe insulation tubing; and at least one hinge interconnecting said first clam shell portion and said second clam shell portion longitudinally between said first and second ends for pivoting said clam shell portions from an open position adapted to receive the pipe and pipe insulation tubing to a closed position coupled about the pipe and adjacent ends of the pipe insulation tubing.
