The double barbs grab the tubing so firmly I didn't need a single clamp, and the UV-stabilized nylon feels tough enough to leave buried in the garden all season. Snapped two lines while expanding my bed, and these made clean, straight splices in under a minute each.

These barbs are perfect for patching up my soaker hose line, and the sharp edges grab the tubing so tight that I don't worry about leaks at all. The stiff nylon feels like it can handle the heat from the sun all summer long.
