Abstract
A safety assembly for a medicament delivery device is presented that prevents premature activation or firing of the device during shipping or handling. The disclosed safety assembly uses a tubular cover partially contained inside of the housing of the delivery device that is axially slidable relative to the housing from a first position to a second position and then to a third position, the tubular cover having a housing nib and a cap nib, where each of the cap nib and housing nib protrudes radially outward from an outer surface of the tubular cover and are located at a proximal end of the tubular cover. In the first position the housing nib and cap nib are located outside of the housing with the housing nib abutting the terminal proximal face of the housing to prevent axial movement of tubular cover relative the housing.
