A needle hub assembly for coupling to a pen needle delivery device (10) includes an outer cover (30) having a first well (40) receiving the needle hub (16) and inner shield (24) covering a cannula (20) of the needle hub (16). A second well (42) is spaced from the first well (40) and has a dimension for receiving the inner shield (24). In use, the pen delivery device (10) is coupled to the connecting end of the needle hub (16) to withdraw the needle hub (16) and inner shield (24) from the first well (40). The inner shield (24) is inserted into the second well (42) where the inner shield (24) is gripped so that the inner shield can be separated from the needle hub (16) without the user handling the outer cover (30) or the inner shield (24). After use, the needle hub (16) is inserted into the first well (40) and the pen needle delivery device is separated from the needle hub (16). The needle hub (16) is retained within the first well (40) where the outer cover (30) containing the used needle hub and inner shield can be discarded as a single unit.L'invention concerne un ensemble embase d'aiguille destiné à être accouplé à un dispositif (10) d'administration d'aiguille-stylo qui comprend un couvercle externe (30) ayant un premier puits (40) recevant l'embase d'aiguille (16) et une protection interne (24) recouvrant une canule (20) de l'embase d'aiguille (16). Un second puits (42) est espacé du premier puits (40) et a une dimension permettant de recevoir la protection interne (24). Lors de l'utilisation, le dispositif (10) d'administration de stylo est accouplé à l'extrémité de raccordement de l'embase d'aiguille (16) pour retirer l'embase d'aiguille (16) et la protection interne (24) du premier puits (40). La protection interne (24) est insérée dans le second puits (42) au niveau duquel la protection interne (24) est saisie de telle sorte que la protection interne peut être séparée de l'embase d'aiguille (16) sans que l'utilisateur ne manipule le couvercle externe (30) n
