1. A protection device at least partially covering a needle of an injection device, the protection device comprising:
a support for the needle, the support having a peg disposed thereon, wherein the peg is laterally displaceable by a first spring, the first spring configured to extend in a lateral direction; and
a sleeve comprising a distal end intended to come into contact with an injection surface and provided with an orifice intended to allow the needle to pass therethrough, the sleeve being arranged so as to be moveable axially in translation with respect to the support between a first, storage position, a second, injection position, and a third, protection position, wherein the sleeve further comprises a running passageway formed therein,
wherein a second spring is configured to axially move the support relative to the sleeve between the second, injection position to the third, protection position,
wherein the first spring displaces the peg in the lateral direction, within the running passageway of the sleeve, when the sleeve reaches the second, injection position, and
wherein the first spring transitions from a compressed state to an at least partially relaxed state when laterally displacing the peg at the second, injection position.
