The invention relates to an infusion set for an intermittent or continuous administration of a therapeutical substance, such as insulin. The infusion set comprises an infusion part (OB) for insertion into a patient and a connector (OA) for connecting the infusion part with a medical device through a tube (7), the connector being axially displaceable relative to the infusion part. The infusion part comprises an adhesive support (1), a base part (2) with a first set of guiding means (13) and at least two retention devices (4) for locking the connector to the infusion part, a cannula extending from said base part and being in fluid communication with a cavity which is optionally covered with a membrane, the cavity is further adapted to receive a second cannula extending from the connector, which second cannula is in fluid communication with the tube.

1. An infusion set comprising an infusion part for insertion into a patient and a connector for connecting the infusion part with a medical device through a tube, the connector being axially displaceable relative to the infusion part, the infusion part comprising: an adhesive support;a base connected to the adhesive support, the base part including a first set of guides and at least two retention devices for releasably locking the connector to the infusion part, said retention devices extending upwardly from an upper surface of the base;a first cannula extending from said base and being in fluid communication with a cavity, said cavity being adapted to receive a second cannula extending from the connector, wherein said second cannula is in fluid communication with the tube; andthe connector comprising: a second set of guides adapted to fit with the first set of guides and at least two arms adapted to fit with the retention devices, the arms are movable in a laterally inward direction, in a laterally outward direction and in an upward direction away from the base such that movement of the arms in either the laterally inward direction, the laterally outward direction or the upward direction allows disengagement of the arms from the retention devices. 2. An infusion set according to claim 1, wherein the connector is symmetrical relative to a main plane of the connector and relative to a plane perpendicular to the main plane and parallel to the central axis. 3. An infusion set according to claim 1 wherein each arm is flexibly connected to the second set of guides in order for the arms to be able to move in the direction perpendicular to the base. 4. An infusion set according to claim 3, wherein the connection between each arm and the second set of guides comprises at least one groove. 5. An infusion set according to claim 1, wherein the retention devices are flexibly connected to the base. 6. An infusion set according to claim 5, wherein the base comprises at least two flaps on which the retention devices are positioned. 7. An infusion set according to claim 1, wherein the first cannula passes through the adhesive support. 8. An infusion set according to claim 1, wherein the adhesive support is a plaster. 9. An infusion set according to claim 1, wherein the infusion part and the connector comprise two different plastics materials. 10. An infusion set according to claim 1, wherein the visual tone of the connector and the base of the infusion part are different. 11. An infusion set according to claim 1, wherein each of the retention devices comprises a step. 12. An infusion set according to claim 1, wherein each of the retention devices comprises a triangular shape. 13. An infusion set according to claim 1, wherein the tube is fastened to the connector by glue. 14. An infusion set according to claim 1, wherein the medical device is an insulin pump. 15. An infusion set according to claim 1, wherein the first cannula comprises a thermoplastic elastomer (TPE). 16. An infusion set according to claim 15, 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. 17. An infusion set according to claim 1, wherein the infusion part the connector, or both comprise polypropylene. 18. An infusion set according to claim 1, wherein, the second cannula extends from a central part of the connector and the second cannula is recessed relative to a front portion of the central part and at least one of the first set of guides comprises at least two stabilizing fins. 19. An infusion set according to claim 1, further comprising an injector device for the subcutaneous introduction of the first cannula of the infusion part into the skin of a patient. 20. An infusion set according to claim 19, wherein the injector device comprises a housing, a back and longitudinally extending guide, a slidable member which is longitudinally slidable within the housing, a needle for insertion in the cavity of the first cannula, a spring located between the back of the housing and the longitudinally slidable member, locking members for maintaining the spring in a compressed state and release members for disengaging the locking members, and a pivoting member pivotable from a position allowing for insertion of the needle into a position wherein the pivoting member embraces the needle. 21. The infusion set according to claim 1, wherein said cavity is covered with a membrane. 22. The infusion set of claim 1 wherein the second cannula is received into the cavity in a horizontal direction parallel to a main plane of the base part. 23. An infusion set comprising an infusion part and a connector releasably connectable to the infusion part, the infusion part comprising: a base having a lower surface and an upper surface, the upper surface comprising a first guide and a releasable locking member extending upwardly from the upper surface for releasably connecting the infusion part to the connector; anda first cannula extending outwardly from the base,the connector comprising: a second guide adapted to fit with the first guide;an arm operably connected to the second guide for releasably interlocking with the locking member, the arm is movable in a laterally inward direction, in a laterally outward direction and in an upward direction away from the base such that movement of the arm in either the laterally inward direction, the laterally outward direction or the upward direction allows disengagement of the arm from the releasable locking member; anda second cannula extending outwardly from the connector and adapted for reception at least partially within a cavity formed in the base;wherein the first cannula and the second cannula are fluidly connectable. 24. The infusion set of claim 23, wherein the infusion set further comprises an adhesive layer connected to the lower surface of the base. 25.
