Described is a needle safety device comprising a needle hub adapted to couple to an injection device a needle coupled to the needle hub and having a distal tip, a needle shield telescopically coupled to the needle hub and including a biasing element, and a locking element arranged on the needle hub. When the needle shield is in a first axial position, the needle shield covers the distal tip of the needle. When the needle shield is in a second axial position, the needle shield moves proximally relative to the needle hub to expose the distal tip of the needle and the locking element deflects the biasing element. When the needle shield is in a third axial position, the locking element engages the biasing element and the needle shield covers the distal tip of the needle.
