Abstract
A medicament delivery device has a needle, a body and a needle cover which is axially movable from an initial position to a holding position to a locked position in which the needle cover covers the distal end of the needle. The device has a biasing member configured to bias the needle cover distally, and a guide member configured to rotate relative to the needle cover. One of the guide member and the needle cover has a pin and the other of the guide member and the needle cover has a guide path for guiding the pin. The guide path has a first ramp, a second ramp and a locking abutment surface. When the needle cover is in the locked position then the locking abutment surface is configured to engage the pin to prevent the needle cover from moving proximally away from the locked position.
