An injection device (210； 110) is provided that includes a housing (212； 112) adapted to receive a syringe (214； 114) that is movable between a retracted position, in which its needle (218； 118) is contained within the housing, and an extended position, in which its needle (218； 118) extends from the housing (212； 112) through an exit aperture (228； 128). The device (210； 110) includes a drive (230, 231, 232, 234； 130, 131, 132, 134) that acts upon the syringe (214； 114) to advance it from its retracted position to its extended position and to discharge its contents through its needle (218； 118). A syringe carrier (222； 122) is advanced with the syringe (214； 114) and a sleeve (219； 119) restrains the advancement of the syringe carrier (222； 122) as the syringe (214； 114) reaches its extended position. A damping element (225； 125) acts between the syringe carrier (222； 122) and the sleeve (219； 119) to cushion the impact as they come into contact, thereby reducing the transmission of energy from the impact to the components of the drive (230, 231, 232, 234； 130, 131, 132, 134) and preventing their fracture. The damping element (225； 125) also reduces the noise, which may be distressing to a user of the device (210； 110), produced when the syringe carrier (222； 122) and the sleeve (219； 119) come into contact and reduces the pain suffered by a user upon operation of the device (210； 110).
