Locatable devices are provided for subcutaneously securing a catheter in an area to be catheterized. In addition, methods for securing a catheter in a subcutaneous location are also provided. In one embodiment, the device comprises two releasably lockable arcuate members interconnected by a hinge. The ends of the arcuate members move with respect to one another from a closed position in which the side surfaces of the arcuate members are coupled in a facing relationship forming a tubular base with a longitudinal passage for receiving a catheter, to an open position in which the ends of the arcuate members are uncoupled and at least partially spaced from each other. Each member is fastened to an end of a connecting material. The connecting material has a length such that it extends within the passage and forms a tightened loop around a catheter inserted within the device. The device may alternatively comprise two tubular members which rotate about each other to create a tightened loop of connecting material around a catheter in a generally cylindrical passage, or an elastic base and a connecting material which forms a loop around a catheter while the base is in a flexed open position and tightens around the catheter while the base is in a relaxed closed position.
