Abstract: A kink inhibiting device is provided for inhibiting kinking in a length of curved flexible tubing, and in particular IV or drip tubing. The device comprises a pair of U-shaped shell halves which are joined back-to-back at their bight portions by an integral hinge formation. The shell halves each define channels having semi-circular cross-sectional profiles, and are formed with connecting lands carrying studs and complemental apertures for allowing the shell halves to mate with one another. The shell halves each have a radius of curvature (R) which is greater than the maximum radius of curvature at which the flexible tubing starts to kink when unsupported.
