The disclosure provides an apparatus and methods for securing a medical catheter. The apparatus includes a tube wall that defines a lumen extending longitudinally there through. The tube wall comprising: a plurality of flexible fingers extending along a portion of the tube wall, a longitudinal slot disposed between each pair of adjacent fingers, each of the fingers comprising an exterior surface and an interior surface. An outer protrusion extends outwardly from the exterior surface of each finger. An inner protrusion extends inwardly from the interior surface of each finger. The inner protrusions are configured to frictionally engage an outer surface of the medical catheter disposed within the lumen when the plurality of flexible fingers are moved inwardly in response to an external force applied to the outer protrusions.
