An improved readily fabricated catheter having a detectable marker incorporated therein wherein the catheter is a conventional flexible and transparent polymeric tube of any usual or desired length, but wherein one end of which is relieved to define a socket or counterbore of an internal diameter somewhat greater than the normal fluid flow bore of the tubing. The catheter further includes a shorter length of tubing having at one end a usual angled or cut face, and having at its other end a short neck of reduced diameter carrying thereon a detectable metallic, magnetic, or radiopaque marker element. The two components are easily telescoped together over their relatively short lengths to confine the marker between the inside and outside walls of the tubing, and the telescoped portions are sealed together to prevent fluid flow or leakage therethrough.
