An infusion set having an infusion part for insertion into a patient and a connector for connecting the infusion part with a medical device through a tube is provided. The connector is axially displaceable relative to the infusion part. The infusion part includes an adhesive support, a base part with a first set of guiding means and at least two retention devices for locking the connector to the infusion part, a cannula extending from the base part and being in fluid communication with a cavity. The cavity is further adapted to receive a second cannula extending from the connector where the second cannula is in fluid communication with the tube. The infusion set further includes a second set of guiding means that are adapted to fit with the first set of guiding means and at least two arms. The retention devices extend from an upper surface of a main surface of the base part and the arms include means corresponding to the retention members.

The invention claimed is: 1. An assembly for the subcutaneous introduction of a cannula of an infusion part into a patient, the assembly comprising: an infusion part comprising: an adhesive support; a base part including at least two retention devices configured to releasably lock a connector to the infusion part, the retention devices extending from an upper surface of a main surface of the base part; and a cannula extending from the base part and being in fluid connection with a cavity of the infusion part, the cavity being adapted to receive a second cannula extending from the connector and through which a therapeutical substance is administrable; and an injector device comprising an insertion needle configured to releasably receive the infusion part, the insertion needle extending at least partially through at least a portion of the cannula to insert the cannula into the skin of the patient; wherein at least a portion of the adhesive support is connected to a portion of the injector device; and a pivoting member connected to the injector device and pivotable from an insertion position into a protection position, the insertion position configured to allow insertion of the needle into the patient and the protection position configured to protect the needle wherein the pivoting member embraces the needle. 2. The assembly of claim 1, wherein the retention devices are positioned at flexible parts of the base part. 3. The assembly of claim 2, wherein the base part comprises at least two flaps on which the retention devices are positioned. 4. The assembly of claim 1, wherein the cannula passes through the adhesive support. 5. The assembly of claim 1, wherein the retention devices each comprise a step. 6. The assembly of claim 1, wherein the retention devices have a triangular shape. 7. The assembly of claim 1, wherein the cannula comprises thermoplastic elastomers (TPE). 8. The assembly of claim 7, wherein the thermoplastic elastomer is selected from the group consisting of polyester ethers, ECDEL, styrene based TPE, olefin based TPE, urethane based TPE, ester based TPE, amid based TPE, polyolefins and silicone rubbers. 9. The assembly of claim 1, wherein the infusion part comprises polypropylene. 10. The assembly of claim 1, wherein a projecting part of a release liner of the adhesive support is fastened to the injector device. 11. The assembly of claim 1, further comprising a release liner of the adhesive support, the release liner comprising at least two separate pieces. 12. The assembly of claim 11, wherein a portion of each piece of the release liner is attached to the injector device during insertion. 13. An assembly for the subcutaneous introduction of a cannula of an infusion part into a patient, the assembly comprising: an infusion part comprising: an adhesive support; a base part including at least two retention devices configured to releasably lock a connector to the infusion part, the retention devices extending from an upper surface of a main surface of the base part; and a cannula extending from the base part and being in fluid connection with a cavity of the infusion part; and an injector device comprising: a housing comprising a longitudinally extending guide; a slidable member adapted to longitudinally slide relative to the housing; a needle connected to the slidable member, the needle configured for insertion at least partially through the cannula to insert the cannula into the skin of the patient, a spring located between a back portion of the housing and the longitudinally slidable member; and a pivoting member connected to the injector device and pivotable from an insertion position into a protection position, the insertion position configured to allow insertion of the needle into the patient and the protection position configured to protect the needle wherein the pivoting member embraces the needle. 14. The assembly of claim 13, wherein the pivoting member is fastened to the slidable member. 15. The assembly of claim 14, wherein the insertion position of the pivoting member is an insertion angle between about 45° and about 180°, the insertion angle measured in relation to a central axis of the needle. 16. The assembly of claim 14, wherein the insertion position of the pivoting member is an insertion angle between about 80° and about 180°, the insertion angle measured in relation to a central axis of the needle. 17. The assembly of claim 14, wherein the insertion position of the pivoting member is an insertion angle between about 90°, the insertion angle measured in relation to a central axis of the needle. 18. The assembly of claim 13, wherein the pivoting member is placed substantially parallel to the housing when the pivoting member is in the position where the pivoting member embraces the needle. 19. The assembly of claim 13, wherein the pivoting member is placed in an embracing angle with respect to the housing between about 0° and about 180° when the pivoting member is in the position where the pivoting member embraces the needle. 20. The assembly of claim 13, wherein the pivoting member is placed in an embracing angle with respect to the housing between about 90° and about 180° when the pivoting member is in the position where the pivoting member embraces the needle. 21. The assembly of claims 13, wherein the pivoting member can embrace the needle when the slidable member is in a forward position and the spring is in a released state. 22. The assembly of claim 13, wherein the needle is destroyed and secured in the pivoting member in the protection position. 23. The assembly of claim 13, wherein the assembly further comprises locking means for maintaining the pivoting member in the protection position. 24. The assembly of claim 13, the pivoting member has fixing means for releasably fastening a part of the adhesive support to the pivoting member. 25. The assembly of claim 13, wherein a projecting part of a release liner of the adhesive support is unreleasably fastened to the housing. 26. The assembly of claim 13, further comprising a release liner of the adhesive support, the release liner comprising at least two separate pieces. 27. The assembly of claim 26, wherein each piece of the release liner is attached to the pivoting member during insertion and the projecting part of the second piece of the release liner is attached to the housing during insertion.
