Claim 0:
1. A connector for connecting a medical injection device, comprising a barrel and a needle extending from a distal tip of the barrel, to a container comprising a pierceable septum, the connector comprising:
an inner deformable cover extending along a cover axis, the inner deformable cover comprising a proximal connection part configured to engage the distal tip of the barrel, a distal portion pierceable by the needle, an inner body that defines an inner volume, and at least one deformable portion configured to form a bulge; and
an outer rigid cover enclosing the inner deformable cover and comprising a distal adaptor configured to engage the container, the outer cover being configured such that a needle tip extends into the distal adaptor when the proximal connection part of the inner deformable cover engages the distal tip of the barrel, the outer rigid cover being fixed to the inner deformable cover such that the inner deformable cover and the outer rigid cover form a single assembly,
wherein the inner deformable cover defines a first flange that abuts against a groove of a proximal part of the outer rigid cover such that the proximal connection part of the inner deformable cover is maintained in a fixed position relative to the outer cover, and
wherein the inner deformable cover is compressible along the cover axis between:
a relaxed configuration wherein the distal portion of the inner deformable cover covers the needle tip and the deformable portion has a diameter greater than a diameter of the rest of the inner body and
a compressed configuration wherein the distal portion is pierced by the needle, the needle tip extending distally out of said distal portion, the deformable portion forming the bulge when the inner deformable cover is in the compressed configuration.
