Claim:
1. A device for medicament delivery with syringe-like usability, comprising: a grip having proximal and distal grip parts with at least one projection; a plunger rod substantially rotationally fixed relative to the grip by cooperating with the at least one projection, whereby the proximal and distal grip parts are rotationally fixed relative to each other; and a locking mechanism configured for intermittent injection of defined doses of medicament, to allow at least a certain movement of the plunger rod when in a delivery position, and to substantially inhibit movement of the plunger rod in a longitudinal direction of the device for dose delivery when in a locking position, wherein the locking mechanism comprises at least one rotatable part that is substantially fixed in the longitudinal direction, that is rotatable relative to the grip, and that interacts with the plunger rod; and an indicator drum configured for rotation by a force of a resilient member when a dose has been injected; wherein at least one of a projection of the rotatable part and at least one projection of the indicator drum interacts with at least one of a channel and a projection of the plunger rod, such that pulling the plunger rod in a distal direction is substantially inhibited by interaction of the indicator drum with the plunger rod.
