The present invention relates to a latching device for a wing arrangement (3) for an aircraft (1), which wing arrangement (3) includes a wing (9) comprising a base section (11) and an outboard tip section (13) connected base section (11) to be pivotable between a deployed position and a stowed position in which the spanwise length of the wing (9) is smaller than in the deployed position. The latching device (27) comprises a support structure (29), a latching bolt (35) having a longitudinal axis (36) and being slidably supported by the support structure (29) such that the latching bolt (35) is movable between a retracted position and an extended position. In the extended position the latching bolt (35) extends further from the support structure (29) than in the retracted position. The latching device (27) further comprises at least one first hydraulic actuator (47a) and at least one first connector assembly (38a) adapted to be connected to a first hydraulic system of an aircraft (1) and to supply the at least one first hydraulic actuator (47a) with pressurized hydraulic fluid, and at least one second hydraulic actuator (47b) and at least one second connector assembly (38b) adapted to be connected to a second hydraulic system of an aircraft (1) and to supply the at least one second hydraulic actuator (47b) with pressurized hydraulic fluid. The at least one first connector assembly (38a) is separated from the at least one second connector assembly (38b). The at least one first hydraulic actuator (47a) and the at least one second hydraulic actuator (47b) are adapted to effect movement of the latching bolt (35) from the extended position into the retracted position independent of the other one of the at least one first hydraulic actuator (47a) and the at least one second hydraulic actuator (47b).
