A catheter has a needle tip protector (12) within a hub (14), and a needle (16) secured to a housing and with two unequal biasing members (18,20) between housing and protector so that as the needle is withdrawn from the hub the protector is extended to an oblique position. The members are pref. two coiled wires with different lengths or biasing strengths, and which may be encased in a sleeve (28).
