A device for gripping a catheter, including a first jawhaving a first exterior side and a first radial passage. Thedevice has a second jaw having a second exterior side,opposite the first exterior side, and a second radialpassage. The device also has a resilient joint connectingthe first and second jaws so that manual compression of thefirst exterior side toward the second exterior side causesrelative rotation between the first and second jaws thatmutually aligns the first and second radial passages, suchthat the catheter can be inserted through the first andsecond radial passages, and so that releasing the manualcompression causes the first and second jaws to rotate sothat the first and second radial passages are no longermutually aligned and so that the catheter passes through andis gripped by the device along mutually aligned first andsecond central axes.
