1. A needle (10) having a distal end (11), a proximal end (12) and a rod (13) located between them, as well as a point (14) at its distal end (11), and equipped with a protective device (20) for protection against injuries by the needle point (14), and the protective device (20) is installed with the possibility of sliding movement along the needle shaft (13) between the first position at the proximal end (12) of the shaft (13) and the second position at the distal end (11) of the needle ( 10) and has a closed housing (21, 22) with a proximal opening (23) and a distal opening (24) for the needle rod (13) to pass through them, while when the safety device (20) is installed in the second position, the needle point (14) is located inside the body (21, 22), and the protective device (20) contains a shutter (30) configured to overlap the distal opening of the body (21, 22) when the needle point (14) is inside the body (21, 22), characterized in that that the shutter (30) contains at least one locking element (31) is made with the possibility of sliding movement from the first position, offset relative to the specified distal hole (24), to the second position opposite the distal hole (24) and is configured to interact with the activating component (32, 33), which is mounted on the shaft (13) of the needle with the possibility of sliding movement along it, and on the shaft (13) of the needle there is a drive element (35), which limits the movement of the activating component (32, 33) along the shaft of the needle in the distal direction, and the activating component (32, 33) is configured to abut against the drive element (35) as a result of the specified movement of the safety device (20) from its first position to the second and with a1. Игла (10), имеющая дистальный конец (11), проксимальный конец (12) и расположенный между ними стержень (13), а также острие (14) у ее дистального конца (11), и снабженная защитным устройством (20) для защиты от травм острием (14) иглы,пр
