1. A medicament delivery device comprising:
a needle for injecting a medicament;
a body having a proximal end and a distal end;
a needle cover, wherein the needle cover is axially movable relative to the body from a holding position in which the needle protrudes from the distal end of the needle cover for injecting the medicament, to a locked position in which the needle cover covers a distal end of the needle;
a biasing member configured to bias the needle cover axially in a distal direction; an inner housing comprising an aperture;
a collar located at least partially within the inner housing and configured to rotate relative to the inner housing, wherein the collar comprises an arm; and
a rotational member for rotating the collar from a first position to a second position,
wherein the needle cover is arranged radially outwardly from the inner housing, and wherein when the needle cover is in the locked position and the collar is in the second position then the arm extends radially through the aperture to a blocking position and contacts a proximal end of the needle cover to block proximal movement of the needle cover away from the locked position.
