A cap ( 16 ) is provided for the type of injection device ( 1 ) which presents a needle assembly ( 11 ) to the exterior thereof for removal after use. The cap is of two part construction with a shell ( 17 ) of hard material, having opposite inwardly flexible tongues ( 19 ) defined by slots in the shell, and an over-mould ( 18 ) of relatively soft deformable material, extending over at least the tongues and the slots. The tongues are squeezable towards each other through the over-mould to grip the needle assembly when the cap is fitted after an injection, thus enabling the needle assembly to be removed with the cap so that the user does not come into contact with the used needle.
