Described is a safety needle device (1) comprising a needle hub (1.1) including a guide track (1.1.1), a needle (1.2) coupled to the needle hub (1.1 ), and a needle shield (1.3) telescopically coupled to the needle hub (1.1). The guide track (1.1.1) includes a first axial section (1.1.3), a second axial section (1.1.4), and a locking section (1.1.9). The needle (1.2) has a distal tip (1.2.1 ). The needle shield (1.3) includes a radial protrusion (1.3.1) adapted to engage the guide track (1.1.1). When the needle shield (1.3) is in a first axial position (PA1) and a first angular position (P1 ) relative to the needle hub (1.1), the radial protrusion (1.3.1) is in the first axial section (1.1.3) and the needle shield (1.3) covers the distal tip (1.2.1) of the needle (1.2). When the needle shield (1.3) is in a second axial position (PA2) and a second angular position (P2), the radial protrusion (1.3.1 ) is in the second axial section (1.1.4) and the distal tip (1.2.1 ) of the needle (1.2) is exposed from the needle shield (1.3). When the needle shield (1.3) is in a third axial position (PA3) and a third angular position (P3), the radial protrusion (1.3.1 ) is adjacent the locking section (1.1.9) and the needle shield (1.3) covers the distal tip (1.2.1 ) of the needle (1.2). The locking section (1.1.9) is adapted to engage the radial protrusion (1.3.1) to prevent movement of the needle shield (1.3) to the second axial position (PA2). A spring (1.5) applies an axially biasing force and a rotationally biasing force on the needle shield (1.3) relative to the needle hub (1.1). The axially biasing force biases the needle shield (1.3) toward the first axial position (PA1) and the third axial position (PA3), and the rotationally biasing force biases the needle shield (1.3) toward the third angular position (P3) relative to the needle hub (1.1).On décrit un dispositif de protection daiguille (1) qui comprend un raccord daiguille (1.1) comportant un chemin de guidage (1.1.1) une
