Abstract:
1. Sleeve having a longitudinal axis (A) intended to be mounted on a container of an injection device, said container being provided at its proximal end with at least one outer flange, said sleeve comprising at least one outer body, said sleeve being provided with at least one inner radial projection intended to prevent the proximal movement of said outer flange with respect to said sleeve once said sleeve is mounted on said container, characterized in that said sleeve is further provided with at least one inner longitudinal projection extending distally from said inner radial projection and intended to limit the radial movement of said outer flange with respect to said sleeve, said inner radial projection and inner longitudinal projection being provided on at least one longitudinal leg connected to said outer body by a deformable bridge, said deformable bridge being capable of being deformed with respect to said outer body to allow radial deflection of said longitudinal leg, outwardly when a distal pressure is exerted on said inner radial projection, and inwardly when a proximal pressure is exerted on said inner radial projection, wherein said deformable bridge is located proximally from said inner radial projection and said inner longitudinal projection.
