Injection device for injection of set liquid medication dose contains case, reservoir for medication, piston, made with possibility of axial travel in reservoir, means for setting of dose, injection means, providing performing injection of set dose, press button, holding device for holding press button in second position when injection device is brought in action in order to perform injection of set dose, detachable cap and receiving component. Injection device contains piston rod for realisation of discrete piston forward movement in reservoir in order to push out set volume of liquid medication. Press button is functionally connected with means for dose setting and with injection means and is made with possibility of axial travel between first position, corresponding to set dose, and second condition, corresponding to bringing injection means for performing set dose injection in action. Holding means is functionally connected with means for dose setting in such a way that when means for dose setting is brought into action in order to set dose, holding means is automatically deactivated. Holding component is made with possibility of resting against cap or connection with it when it is installed on injection device. Receiving component is functionally connected with means for dose setting with provision of automatic deactivation of holding means and displacement of press button from first into second position, when cap is installed on injection device.
