1. A device for connecting a reservoir to a fluid pathway in a medicament delivery apparatus, comprising:
a main body having a service area configured to house a needle in fluid communication with a fluid pathway;
a reservoir extending along a longitudinal axis and housed within the main body, the reservoir being filled with a medicament to be delivered in the fluid pathway through the needle and comprising an end surface configured to be pierced by the needle and a plunger movable within the reservoir along an axial direction parallel to said longitudinal axis;
a piston movable along said axial direction;
wherein the device comprises a trigger mechanism configured to drive the device to move from an initial operative configuration at which the axial movement of the piston causes an axial movement of the reservoir with respect to the main body to a final operative configuration at which the axial movement of the piston causes an axial movement of the plunger within the reservoir; and
wherein the trigger mechanism comprises a thrusting member which is engaged with the piston when the device is at said initial operative configuration and operatively disengaged from the piston when the device is at said final operative configuration.
