SOLUTION: The invention relates to a shield 1 for covering at least part of a needle 2 and needle hub 6 of a needle assembly unit. The shield 1 has an open proximal end 1a, a closed distal end 1b, and a wall 4 extending from the proximal end 1a to the distal end 1b and defining an interior cavity 5 for receiving at least part of the needle 2 and needle hub 6, characterized in that it comprises at least a first retainer 9 and a second retainer 8 which are defined on the wall 4, extending into the cavity 5. The first retainer 9 and the second retainer 8 are designed to be able to resiliently and releasably engage part of the needle assembly unit to secure the shield 1 thereto. The first retainer 9 and the second retainer 8 are different in at least their shape or one of their dimensions from each other. The invention also relates to a needle assembly unit and to an injection device, each comprising such a shield. COPYRIGHT: (C)2009,JPO&INPIT
