A holder for cartridges or containers for medicaments in injectable form comprising an elongated housing having a pocket for the cartridge, a head assembly including an elongated plunger rod adapted to be attached to the cartridge plunger for actuating the same to effect discharge of medicament from the cartridge and means operatively connecting the head assembly to one end of the housing for actuating a shank portion of the head assembly axially (longitudinally) in the housing. The head assembly and housing is made of dissimilar materials to facilitate relative rotation of the head assembly and housing and resist slippage when the shank exerts an axial force on the cartridge to seat it in the housing.
