The gate (100) also has a locking device (110) for locking the barrier sheet (102) in the locked position. The locking device (110) includes or is connected to a locking indicator which indicates a first state corresponding to the locked state of the locking device (110) and a second state corresponding to an unlocked state of the locking device (110). ## Claims ### Claim 1 A child safety gate for a passageway, such as a door opening, comprising: a flexible retractable barrier sheet which is wound on a roller mountable to one side of the passageway, said barrier sheet being moveable between a first position in which the barrier sheet is retracted and the passageway is open, and a second position in which the barrier sheet is extended and has an outer free end attached to an opposite side of the passageway which is then closed by the barrier sheet; and a locking device which is configured to lock the barrier sheet in the extended position in which the passageway is closed; wherein the locking device includes or is operatively connected to a locking indicator capable of indicating if the locking device is in a first state corresponding to a locked state of the locking device or a second state corresponding to an unlocked state of the locking device. ### Claim 2 (depends on 1) The child safety gate according to claim 1, wherein the locking indicator forms a part of the locking device. ### Claim 3 (depends on 1) The child safety gate according to claim 1, wherein the state of the locking device automatically switches between its locked and unlocked states when a user is locking or unlocking the barrier sheet. ### Claim 4 (depends on 1) The child safety gate according to claim 1, wherein the locking indicator is a visual indicator, a tactile indicator or a sound indicator or any combination of such indicators. ### Claim 5 (depends on 4) The child safety gate according to claim 4, wherein the locking indicator comprises a visual and/or tactile a protrusion integrated in the locking device. ### Claim 6 (depends on 5) The child safety gate according to claim 5, wherein the locking indicator protrusion is stationary in the locking device and wherein an associated locking member is spring biased and movable relative to the protrusion. ### Claim 7 (depends on 4) The child safety gate according to claim 4, wherein the locking indicator comprises a light emitter which switches on or off when the locking device is locked or unlocked. ### Claim 8 (depends on 4) The child safety gate according to claim 4, wherein the locking indicator comprises a light emitter which switches color when the locking device is locked or unlocked. ### Claim 9 (depends on 4) The child safety gate according to claim 4, wherein the locking indicator comprises means capable of generating an audio signal for notifying a user if the locking device is locked or unlocked. ### Claim 10 (depends on 4) The child safety gate according to claim 4, wherein the locking indicator comprises means capable of generating an audio signal when the locking device is locked and a user is trying to open the child safety gate. ### Claim 11 A locking device for a child safety gate, said gate having a flexible barrier sheet wound on a roller and configured to be rolled out and detachably engaged with a holding device spaced from the roller, said locking device being associated with the roller or the holding device, wherein the locking device comprises a locking indicator having a visual and/or tactile protrusion integrated in the locking device, said locking indicator indicating a locked state where the locking device locks the barrier sheet and prevents movement of the barrier sheet, and an unlocked state where the locking device allows movement of the barrier sheet. ### Claim 12 (depends on 11) The locking device according to claim 11, wherein the locking indicator protrusion is stationary and associated with a spring biased locking member which is movable relative to the protrusion. ### Claim 13 (canceled) ### Claim 14 (canceled) ### Claim 15 A child safety gate comprising a flexible retractable barrier sheet being moveable between an open and a closed position, and a locking device being capable of locking the barrier sheet in the closed position, wherein said locking device includes or is operatively connected to a locking indicator capable of indicating a first state corresponding to a locked state of the locking device, and a second state corresponding to an unlocked state of the locking device. ### Claim 16 A child safety gate for a passageway, such as a door opening, comprising: a flexible retractable barrier sheet which is wound on a roller, said barrier sheet being moveable between a first position in which the barrier sheet is retracted, and a second position in which the barrier sheet is extended; and a locking device which is configured to lock the barrier sheet in the extended position in which the passageway is closed; wherein the locking device includes or is operatively connected to a locking indicator capable of indicating if the locking device is in a first state corresponding to a locked state of the locking device or a second state corresponding to an unlocked state of the locking device.
