A flow detector has a housing (1) with tongues (8), which allow to anchor it to a support to withstand pulling forces. The housing further comprises pegs (41) provided to mate with openings or recesses in the same support, which allow to secure it against lateral forces. The tongues (8) and pegs (41) are mounted to a hull (7) of a housing (1) of the detector, which carries on its opposite side an inlet (4a) and an outlet (4b) for the fluid to be measured. Connectors (5) are provided on the same side as the tongues (8) and the pegs (41) for connecting the detector to an external system. This design is robust and allows to mount the detector to the support in quick and secure manner.

The flow detector of claim 1 wherein said first side is formed by a first surface of said housing and said second side is formed by a second surface of said housing. 5. The flow detector of claim 1 wherein said tongues have free ends suited for insertion into openings of said external support. 6. The flow detector of claim 5 wherein each tongue comprises a head and a neck, wherein said neck extends between said second side of said housing and said head and wherein said neck has a diameter smaller than a maximum diameter of said head, and in particular wherein said head is tapered towards an end facing away from said housing. 7. The flow detector of claim 1 wherein said tongues are arranged with rotational asymmetry in respect to any axis of rotation extending through said first and second side of said housing. 8. The flow detector of claim 1 wherein said housing comprises, in addition to said connectors and said tongues, at least one peg projecting perpendicularly from said second side of said housing, wherein a diameter of said peg remains constant or decreases with increasing distance from said second side of said housing. 9. The flow sensor of claim 1 wherein said housing comprises a hood forming said first side of said housing, wherein said tongues are integrally attached to said hood. 10. The flow sensor of the claim 9 wherein said housing comprises, in addition to said connectors and said tongues, at least one peg projecting perpendicularly from said second side of said housing, wherein a diameter of said peg remains constant or decreases with increasing distance from said second side of said housing, and wherein said peg or pegs is/are integrally attached to said hood. 11. The flow detector of claim 1 further comprising a internal printed circuit board, wherein said sensor chip is mounted to a first side of said internal printed circuit board and said connectors project from a second side of said internal printed circuit board. 12. The flow detector of claim 11 wherein said internal printed circuit board forms at least part of said second side of said housing. 13. The flow detector of claim 11 wherein said sensor chip lies flush against said internal printed circuit board. 14. The flow detector of claim 11 wherein said housing comprises a hood forming said first side of said housing and wherein said internal printed circuit board resides in a recess of said hood and is held in said recess by a frame pushing towards said second side of said plate. 15. The flow detector of claim 14 further comprising a sealing ring arranged between said frame and said plate for preventing said fluid from exiting at said second side of said housing. 16. The flow detector of claim 11 wherein said housing comprises a wall forming said first side of said housing, wherein said channel is formed by a groove extending at an inner side of said wall and covered by said internal printed circuit board. 17. The flow detector of claim 1 wherein said flow channel extends in a plane parallel to said first side of said housing and has a first end connected to said inlet and a second end connected to said outlet, wherein said first end and/or said second end is/are looped around at least 180° of said inlet and/or outlet, respectively. 18. The flow detector of claim 1 further comprising at least one first and at least one second screw holder for receiving an attachment screw or attachment pin, wherein said at least one first screw holder is structured to hold a screw in a direction parallel to said first and said second sides of said housing and said at least one second screw holder is structured to hold a screw in a direction perpendicular to said first and said second sides of said housing. 19. The flow detector of claim 18 further comprising at least one first and at least one second screw holder on a third side of said housing and at least one first and at least one second screw holder on a fourth side of said housing, wherein said fourth side is opposite said third side. 20. The flow detector of claim 18 wherein said first screw holder comprises a first through-hole and said second screw holder comprises a second through-hole, wherein said first and said second through-holes intersect. 21. The flow detector of claim 1 wherein said connectors comprise pins projecting perpendicularly from said second side of said housing. 22. The flow detector of claim 21 wherein said pins are straight. 23. The flow detector of claim 21 wherein said pins have a first section extending perpendicularly from said second side of said housing and a second section extending at a right angle to said first section. 24. A flow detector for measuring a flow of a fluid comprising a housing having opposite first and second sides, a hood formed by a single plastic piece and forming said first side of said housing, an inlet and an outlet for said fluid arranged at the first side of said housing, wherein said inlet and said outlet are integrally attached to said hood and extend away from said hood, a flow channel arranged in said housing and connecting said inlet and said outlet, an internal printed circuit board arranged in said hood, a sensor chip arranged on said internal printed circuit board at said flow channel and adapted to measure said flow in said flow channel, electrical connectors connected to said sensor chip for connecting said flow detector to an external system, wherein said connectors extend from the second side of said housing and are mounted to said internal printed circuit board, and a plurality of tongues, in addition to said connectors, integrally connected to said hood and extending perpendicularly to said internal printed circuit board away from the second side of said housing for mechanically mounting said housing to an external support. 25.
