A device for installing a catheter tube in a vein by the Seldinger method, once the device has been inserted, has a tubular cylindrical sheath, with a slot running its entire length, mounted on a dilator tube. A cylindrical main portion of the sheath terminates at a distal end edge which flares forwardly and is adjacent a shoulder of the dilator tube for enabling the dilator tube to be withdrawn through the sheath.
