Claim:
An IV-catheter insertion device, comprising: a catheter hub comprising an interior at a proximal end of a catheter tube; a tubular needle holder with an attached hollow needle having a needle tip, the hollow needle extending through the catheter hub and the catheter tube in a ready position such that the needle tip projects distally of a distal end of the catheter tube; a protective barrel is received in the tubular needle holder in the ready position and releasably connected to the catheter hub; a pressure spring arranged between the tubular needle holder and the protective barrel and to displace the tubular needle holder and the protective barrel axially away from each other when released; and wherein a manually operable holding member is provided between the tubular needle holder and the protective barrel and holds the tubular needle holder in the ready position on the protective barrel against a bias force of the pressure spring so that after the holding member is released, the pressure spring moves the tubular needle holder into a protective position in relation to the protective barrel, in which the hollow needle is positioned in the protective barrel.
