1. Injection device (1), in particular an autoinjector, which is designed to be adjustable from a storage position to an injection position, comprising a support housing (2), which has a distal end (11) to be applied to a patient (10) and a proximal end (12) opposite the latter, between which a longitudinal axis (13) extends,an activating sleeve (9), which surrounds the support housing (2) at least partly, whereby the distal end (11) of the support housing (2) projects over the activating sleeve (9), and the activating sleeve (9) can be displaced in axial direction relative to the support housing (2),a cartridge (3) containing the medicine (14) to be administered in an injection procedure, whereby the cartridge (3) is mounted in the support housing (2),a first drive unit (4) which is in active connection with the cartridge (3) and the activating sleeve (9) and can be triggered by means of the activating sleeve (9),a safety device (5), which secures the first drive unit (4) prior to its activation for the injection procedure in position relative to the support housing (2),a needle arrangement (6), which is arranged ahead of the cartridge (3) in the storage position of the injection device (1) in the section of the distal end (11), and both needle ends (21, 22) of a cannula (20) are arranged inside the support housing (2),a needle protection element (7) which can be displaced from a non-active position into a position which covers the needle end (21) projecting over the distal end (11) of the support housing (2) after the injection procedure,a second activatable drive unit (8), which displaces the needle protection element (7) from the non-active position into the covering position,whereinthe support housing (2) is surrounded over the most part of its longitudinal extension between the distal and proximal end (11, 12) by the activating sleeve (9) and the needle protection element (7) with the second drive unit (8) interacting therewith is arranged radially between the support housing (2) and the activating sleeve (9), as viewed in axial cross section.
