The fluid is generally a medication, e.g., insulin. The cannula is in fluid communication with a fluid passageway surrounded by a projection on the cannula housing that includes one or more rail-like extensions acting as guides. A connector connects the cannula housing to a fluid delivery system, e.g., an infusion pump. The connector includes a needle, one or more guide arms that slide over the rail-like extensions to guide the needle into the self-sealing septum, and one or more locking arms, with barbs at the end, to connect with corresponding recesses in the cannula housing. An introducer having one or more similar guide arms and locking arms, and a longer needle, may be used to insert the cannula into the patient. ## Claims ### Claim 1 A connector device to deliver fluid from a fluid delivery device to a body of a user, the connector device comprising: separate first and second guide arms having no physical connection therebetween, each of the separate first and second guide arms having opposing inner and outer longitudinal sides, wherein, for each guide arm, the outer longitudinal side is flat along substantially the entire length thereof and the inner longitudinal side has an arcuate profile along substantially the entire length thereof, said inner side of the first guide arm facing the inner side of the second guide arm; and a longitudinally-extending connecting needle that is parallel to said guide arms and is disposed laterally spaced apart from, and in-between, said first and second guide arms, wherein the needle has a distal tip and the guide arms have respective distal ends, and the distal ends of the first and second guide arms extend beyond the needle's distal tip. ### Claim 2 (depends on 1) The device of claim 1, wherein the connector device is symmetrical about its longitudinal axis such that it is reversible. ### Claim 3 (depends on 1) The device of claim 1, wherein the inner longitudinal side of each of said first and second separate guide arms is concave. ### Claim 4 (depends on 1) The device of claim 1, wherein the connector device further includes a plurality of locking arms, each said arm having a barb associated therewith. ### Claim 5 (depends on 1) The device of claim 1, wherein the fluid delivery device is an infusion pump. ### Claim 6 (depends on 1) The device of claim 1, wherein the connector is made of material selected from the group consisting of polycarbonate and polypropylene. ### Claim 7 (depends on 1) The device of claim 1, wherein the needle is stationary at all times with respect to the first and second guide arms. ### Claim 8 (depends on 1) The device of claim 1, wherein the device is configured to be detachably connected to a cannula housing having a cannula for delivering said fluid to the user's body. ### Claim 9 (depends on 1) The device of claim 1, wherein the fluid is insulin. ### Claim 10 A connector device to deliver fluid from a fluid delivery device to a body of a user, the connector device comprising: a first guide arm having opposing inner and outer longitudinal sides, wherein the outer longitudinal side is flat along substantially the entire length thereof and the inner longitudinal side has a concave profile along substantially the entire length thereof; a second guide arm separate from said first guide arm, said second guide arm having opposing inner and outer longitudinal sides, wherein the outer longitudinal side is flat along substantially the entire length thereof and the inner longitudinal side has a concave profile along substantially the entire length thereof, wherein the inner side of the first guide arm faces the inner side of the second guide arm; a longitudinally-extending connecting needle that is parallel to said guide arms and is disposed laterally spaced apart from, and in-between, said first and second guide arms; and a locking arm having a barb. ### Claim 11 (depends on 10) The device of claim 10, wherein the needle has a distal tip and the guide arms have respective distal ends, and the distal ends of the first and second guide arms extend beyond the needle's distal tip ### Claim 12 (depends on 10) The device of claim 10, wherein the connector device is symmetrical about its longitudinal axis such that it is reversible. ### Claim 13 (depends on 10) The device of claim 10, wherein said locking arm includes a grip. ### Claim 14 (depends on 10) The device of claim 10, further including a plurality of locking arms, each said locking arm having a barb associated therewith. ### Claim 15 (depends on 10) The device of claim 10, wherein the connector device is made of material selected from the group consisting of polycarbonate and polypropylene. ### Claim 16 (depends on 10) The device of claim 10, wherein the needle is stationary at all times with respect to the first and second guide arms. ### Claim 17 (depends on 10) The device of claim 10, wherein the fluid is insulin.
