摘要：
The invention relates to a finger guard for an injection device for administering a dose of a liquid medicament, the finger guard comprising two inwardly biased spring arms arranged for bearing against a protective needle shield arrangeable at a hollow needle, the finger guard further having a respective locking arm assigned to each spring arm biased in a distal direction thus bearing against the respective spring arm when the protective needle shield is in place, wherein the spring arms are arranged to move inwards when the protective needle shield is removed thus allowing the locking arms to move distally into a position where they prevent the spring arms from being pushed outward again.
