17. A device according to claim 1 ,

wherein a sensor means detects the presence of the injection member connected to the device.

18. A device according to claim 17 ,

wherein the sensor means is designed to enable an output of a liquid from the device when the presence of the injection member is detected.

19. A device according to claim 17 ,

wherein the sensor means is designed to enable an output of a liquid from the device when the presence of the injection member is not detected.

20. A removable injection member designed to be mounted to a system for preparing a beverage from a food substance contained in a capsule by injection of a liquid into the capsule provided by the system, the injection member comprising

a support member and at least one needle element for receiving a liquid under pressure, the injection member comprises means for a releasable connection from below to a support of such a system, and

wherein the means for connecting the injection member to the support of the system is a latch member.

21. A removable injection member according to claim 20 ,

wherein the support member is a ring shaped disc member.

22. A removable injection member according to claim 20 ,

wherein the latch member is formed as an integral part of the support.

23. A removable injection member according to any of claim 20 ,

wherein a convex part is designed to protrude from a lower face of the injection member in a direction that is the same as the needle element.
