Device for medicament delivery with syringe-like usability having a restraining mechanism

A device for medicament delivery with syringe-like usability, comprising:

• at least one grip, wherein the grip comprises separate proximal and distal grip parts having at least one projection;
• at least one medicament container holder;
• and
• at least one rotatable part which is rotatable relatively to a plunger rod and the grip and interacts with the grip to substantially inhibit movement of the plunger rod in a longitudinal direction for dose delivery when the plunger rod is in at least one locking position until being rotated;
• wherein the plunger rod is 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;
• the medicament container holder is movable toward the grip in the longitudinal direction of the device, and rotation of the rotatable part is restrained by at least one restraining member abutting or being connected to the rotatable part and the grip until the medicament container holder is moved toward the grip for interacting with the at least one restraining member.
