1. A panic lock for fitting in a door, said panic lock comprising: a lock case;a dead bolt;a latch bolt;an operating bar that can move in the lock case between three positions, respectively a first, second and third position, whereby the operating bar can cooperate with the dead bolt to retract the dead bolt in the lock case by a movement of the operating bar from the first to the second position, and which can cooperate with the latch bolt to retract the latch bolt in the lock case by a further movement of the operating bar from the second position to the third position;a cylinder lock with a lip that can be rotated in the lock case to move the operating bar; two handle followers or handles that can turn coaxially with respect to one another in the lock case, respectively an inside handle follower or handle and an outside handle follower or handle that are pushed to a rest position by means of a spring;a finger plate and a panic plate that are affixed so that they can turn in the lock case, respectively a panic plate in order to, upon turning, retract the dead bolt by operating the inside handle follower or handle, and a finger plate to retract the latch bolt upon turning;whereby the inside handle follower or handle is coupled to the finger plate and the panic plate such that an angular displacement of the inside handle follower or handle from the rest position causes a movement of the panic plate that hereby moves the operating bar from the first to the second position, and that after a first phase of the angular displacement of the inside handle follower or handle the finger plate is carried along in the angular movement to retract the latch bolt,whereby the panic lock is provided with an operatable coupling for the mutual coupling or uncoupling of the turning movement of both handle followers or handles with respect to one another,wherein the coupling can be operated by a coupling rod that is slidably provided in the lock case so that it can move between two positions corresponding respectively to a coupled and uncoupled position of the handle followers or handles and whereby the coupling rod is provided with a catch that can cooperate with the operating bar for coupling the handle followers or handles when it is moved from the first to the third position, andwherein the catch can be put in two positions or states depending on the desired function of the panic lock, ‘position B’ that is such that upon a movement of the operating bar from the first to the third position, the coupling rod is only carried along during the movement from the second to the third position, and, a ‘position D’,whereby upon a movement of the operating bar the coupling rod is carried along from the first to the second position. 2. The panic lock according to claim 1, wherein for each position B and D of the catch the operating bar is provided with an end stop, whereby, the distance from the catch in the position B to the end stop corresponding to the position B of the catch is greater than the distance from the catch in the position D to the end stop corresponding to this position D of the catch. 3. The panic lock according to claim 1, wherein the coupling rod is provided with at least one threaded hole in a position corresponding to the aforementioned position D of the catch andwherein the catch is formed by a screw that can be screwed in the threaded hole,hereby the screw is held in a recess of the operating bar so that it can move and the screw's edge forms an aforementioned end stop for the catch. 4. The panic lock according to claim 3, wherein the coupling rod is provided with a second threaded hole in a position corresponding to the aforementioned position B of the catch,whereby the screw that acts as a catch can be moved from the first threaded hole to the second threaded hole. 5. The panic lock according to claim 3, wherein the first and/or the second threaded holes are accessible through an opening or openings in the lock case from the outside of the panic lock to move and/or screw in and/or out the aforementioned screw. 6. The panic lock according to claim 1, wherein the panic lock is provided with an interlock that enables the coupling rod to be locked or unlocked with respect to the lock case in the coupled position of the coupling rod. 7. The panic lock according to claim 3, wherein the panic lock is provided with an interlock that enables the coupling rod to be locked with respect to the lock case in the coupled position of the coupling rod,whereby the locking is formed by a screw that can be screwed into a threaded hole in the coupling rod in order to lock the coupling rod,whereby this screw is held in a passage in the lock case so that the screw cannot be moved in the coupling rod. 8. The panic lock according to claim 3, wherein the panic lock is provided with only a single screw, which can be used either as a catch in one of the threaded holes corresponding to the position B or D, or as a lock in the threaded hole at position E for blocking the coupling rod in the coupled position. 9. The panic lock according to claim 1, wherein the coupling rod and the cylinder lock are positioned such that the coupling rod can be moved in the coupled position by turning the lip of the cylinder lock in order to unlock. 10. The panic lock according to claim 1, wherein the coupling is formed by a drive element that is fastened to the panic plate whereby the drive element turns together with this panic plate and can be moved with respect to the panic plate, between a position in which this drive element is within a cam on each of the handle followers or handles and a position in which the drive element is outside the cam. 11. The panic lock according to claim 10, wherein the aforementioned drive element is held in a guide of the coupling rod so that the drive element can rotate, and enables a turn of the drive element around the handle followers or handles. 12. The panic lock according to claim 1, wherein the panic lock is provided with means that enable the panic plate to be tightly connected to the handle follower or handle, that is intended to be used as the inside handle follower or handle. 13. The panic lock according to claim 12, wherein the means that enable the panic plate to be tightly connected to the one or the other handle follower or handle, are formed by a screw that can be screwed in a threaded hole in the panic plate in two possible positions located at a radial distance, respectively one position whereby the screw can cooperate with a single handle follower or handle and another position whereby the screw can engage with the other handle follower or handle. 14. The panic lock according to claim 13, wherein the aforementioned threaded holes in the panic plate are accessible through an opening in the lock case to be able to move the screw from the first position to the second position, depending on which handle follower or handle will be used as the inside handle follower or handle. 15. The panic lock according to claim 1, wherein the operating bar is constructed in two parts, respectively a primary part and a secondary part, that can be moved parallel to one another in the lock case,whereby a transmission is provided between the two parts that is such that a movement of the primary part in a certain direction brings about a movement of the secondary part in the same direction. 16. The panic lock according to claim 15, wherein the primary part can be moved by means of the cylinder lock and/or by means of the panic plate and that the secondary part is provided with a gudgeon that can cooperate with the dead bolt in order to move the secondary part from the locked to the unlocked position or vice versa. 17. The panic lock according to claim 15, wherein the transmission is such that a movement of the primary part brings about a greater movement of the secondary part. 18. The panic lock according to claim 15, wherein the transmission has a freely turning double gearwheel with two sets of teeth, of which one set of teeth meshes with a toothed rack of the primary part, while the other set of teeth meshes with the toothed rack of the secondary part,whereby the sets of teeth of the double gearwheel have a different number of teeth. 19. The panic lock according to claim 15, wherein the panic lock is provided with an additional gearwheel that meshes with the double gearwheel and which is provided with a cam that can cooperate with the lip of the cylinder lock. 20. The panic lock according to claim 1, wherein the dead bolt is a dead bolt that can turn in the lock case.
