Abstract
A medicament delivery device has a needle for injecting medicament, a body and a needle cover. The needle cover is axially movable relative to a locked position in which the needle cover covers the distal end of the needle. The device has an inner housing with an aperture. A collar is located at least partially within the inner housing and is configured to rotate relative to the inner housing. The collar has one or more arms. A rotational member rotates the collar from a first position to a second position. 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 and blocks proximal movement of the needle cover away from the locked position.
