Safety clip for a needle

A safety clip for a needle, the safety clip comprising:

• a proximal portion comprising a proximal wall, the proximal wall defining a proximal aperture for receiving a needle;
• a distal portion comprising a first distal wall connected to a second distal wall, the second distal wall being more distal than the first distal wall, the first distal wall and the second distal wall defining a distal aperture for receiving the needle;
• a clip body extending from the proximal portion to the distal portion;
• and
• a spring arm located between the proximal portion and the distal portion, the spring arm being in contact with the needle, and the spring arm being configured to flex between a first conformation and a second conformation to move the safety clip relative to the needle, wherein:
• when a distal tip of the needle is distal of the second distal wall, the spring arm is in the first conformation, and when the distal tip of the needle is proximal of the second distal wall and distal of the first distal wall, the spring arm is in the second conformation.
