Abstract
The invention relates to an automatic injection device (1) including: a container (6) provided with a needle (8); a housing (3) receiving a container (6) movable relative to the housing (3) between an initial position to an insertion position; a needle shield (12) for receiving the needle (8) and in which the needle (8) is embedded prior to use of the device (1); and, a deshielder (33) coupled to the needle shield (12) by a first connecting arrangement (51) and removably assembled to the distal part of the housing (3) by a second connecting arrangement (44, 45a, 45b, 57). The first and second connecting arrangements are designed so that a rotational movement of the deshielder (33) about the device axis (2) of the device (1) with respect to the housing (3) causes an axial displacement of the needle shield (12) in the distal direction with substantially no rotational movement of the needle shield (12) with respect to the needle (8).
