1. A tool for removing a cap from a medical injection device comprising:
a body and a needle extending distally from the body, the cap covering the needle, wherein the tool comprises a pair of oppositely positioned jaws connected by an elastic interface, each jaw comprising:
a distal portion forming a distal clamp configured to surround at least a part of the cap; and
a proximal portion forming a U-shaped proximal hook portion on the proximal end of each of the pair of jaws, the U-shaped proximal hook portions configured to be removably axially fixed to a body of the medical injection device, wherein the U-shaped proximal hook portions of the jaws are oriented such that each U-shaped opening in the U-shaped proximal hook portions face radially inward,
wherein the elastic interface forming a fulcrum located between the distal portion and the U-shaped proximal hook portions such that a pinching force exerted radially inwardly onto the distal portion of the jaws causes the U-shaped proximal hook portions of the jaws to expand radially outwardly, and
wherein the tool is operable between:
a rest position wherein the U-shaped proximal hook portions of the jaws rigidly engages the body of the medical injection device, the distal portion of the jaws being distant from the cap; and
an operative position wherein the distal portion of the jaws is pinched so that the distal portion engages the cap and the U-shaped proximal hook portions disengage from the body of the medical injection device.
 
12. A medical injection assembly comprising:
a medical injection device including a body, a needle extending distally form the body and a cap covering the needle; and
a tool as claimed in claim 1,
wherein the U-shaped proximal hook portions of the jaws rigidly engage the body of the medical injection device and the distal portion of the jaws is distant from the cap.
 
17. The medical injection assembly of claim 12, wherein the distal portion of each jaw comprises an L-shaped gripping section extending on an inner surface thereof.
