A fluid coupling includes a body including a plurality of segments and one or more links connecting the segments in a substantially annular configuration. At least one of the one or more links may be adjustable to modify a diameter of the body. The body may have a substantially U-shaped a cross-section with a first tapered portion, a second tapered portion, a first planar portion, a second planar portion, and/or a third planar portion. The body may include a first rounded corned and a second rounded corner. The first planar portion may be disposed substantially between the first tapered portion and the first rounded corner, the second planar portion may be disposed substantially between the first rounded corner and the second rounded corner, and/or the third planar portion may be disposed substantially between the second rounded corner and the second tapered portion.
