Abstract:
1. A safe injection device comprising a support sheath having a proximal end and a distal end, a syringe body secured to said support sheath, and a protection sheath suitable for sliding axially between a retracted position in which said protection sheath is retracted into an annular space formed between the syringe body and the support sheath, and an extended protection position in which said protection sheath projects beyond the distal end of the support sheath, the device further comprising at least one retaining member suitable for adopting an active retaining configuration for retaining the protection sheath in the retracted position and, starting from said active configuration, suitable for being urged so as to allow the protection sheath to be extended, the syringe body being secured to the support sheath via a ring having a coupling wall that extends substantially transversely between the syringe body and the support sheath, said wall presenting at least one slot enabling the retaining means to be acted upon from a side of the coupling wall that is opposite from the distal end of the support sheath, and the ring being formed integrally with at least one of the support sheath and the syringe body, wherein the ring constitutes a part that is distinct from at least one of the elements constituted by the syringe body and by the support sheath, and wherein the ring and said element present respective fastener skirts, said skirts coming into contact with each other via axial surfaces whereby the ring and said element are fastened together.
