Description

Locking device, door arrangement comprising such a locking device and method for mounting such a locking device Technical Field The present invention relates to a locking device for a door leaf of a door arrangement with the features of the preamble of claim 1. The invention further relates to a door arrangement having a frame and at least one door leaf pivotally supported at the frame, with the features of the parallel claims. Background Locking devices of the type mentioned at the outset are known from the prior art, for example from EP 3 748 109a 1. Disclosed therein is a locking device having a lock housing, a primary lock fastened at the lock housing, and a plurality of secondary locks fastened at the lock housing, the secondary locks being coupled with the primary lock via a drive rod. A safe and reliable locking can thus be achieved. The installation at the door leaf is usually carried out with the aid of a completely preloaded locking device. This puts a corresponding requirement for milling grooves in the door leaf. In order to maintain or replace the lock parts, the locking device needs to be disassembled and, if necessary, at least partially disassembled. EP 3,045,264 a1 discloses a lock with a bolt element which can be mounted at a door leaf, wherein the bolt element can be operated via a lock mechanism. The lock also has an interface for connecting the drive bolt assembly with the bolt bar. The interface has a connecting element connected to the lock mechanism and an opening provided in the lock housing of the lock, wherein the transmission element passes through the opening and is connected to the connecting element when the bolt device is actuated. Disassembly is required in order to disengage the driver bolt assembly from the lock. Disclosure of Invention The invention is based on the object of facilitating the installation and maintenance of a locking device. It is particularly desirable that one or more drive bolts can be coupled to the drive of the locking device in a simple manner and decoupled if necessary. The invention achieves the object by a locking device having the features of claim 1. The locking device configures and/or determines a door leaf for the door arrangement. The locking device has a lock housing, a drive means fastened at the lock housing, and at least one drive rod extending in a longitudinal direction (lock housing longitudinal direction or drive rod longitudinal direction). The at least one drive rod can each be driven by means of a drive device and can be displaced in the longitudinal direction when driven by means of the drive device. Coupling devices for respectively coupling the drive bolts are fastened to the at least one drive rod. The coupling devices each have a receptacle into which the drive bolt can be introduced by means of the end sections. The coupling device and the drive bolt are each configured such that, when the end section is introduced into the receptacle, the drive bolt is coupled to the coupling device or fastened thereto by a locking. In other words, the drive tongue is locked at or with the coupling device when the end section is pushed into the receptacle (a positive connection in the form of a locking connection is established). By means of the proposed locking device, an automatic coupling or connection of the drive bolt at or with the coupling device can be performed, rather without screwing or without having to pay attention to further mounting steps. The coupling is performed by simply plugging the drive bolt and the coupling device together. A reduced installation time can be achieved due to the simple installation. As the movement of the coupling (introduction or plugging together) is relatively simple, the installation of the locking device can be significantly easier automated. The receiving portion of the drive tongue, which can be introduced by means of the end portion, is open in the direction of the longitudinal direction, preferably only in the direction of the longitudinal direction, in particular away from the drive device. Within the scope of a preferred embodiment, the coupling device can be configured such that the coupling of the drive tongue to the coupling device or to the coupling device can be reversibly decoupled. In other words, the drive bolt can be reversibly disengaged from the coupling device at the coupling device or after locking with the coupling device. This facilitates disassembly or maintenance of the one or more drive bolts. Advantageously, the coupling device can have a housing in which the locking element is movably supported for coupling the drive bolt, wherein the locking element can be displaced between a coupling position in which the locking element engages into the receptacle in the displacement direction for coupling with the drive bolt, and a release position in which the locking element releases the receptacle for decoupling the drive bolt (the locking element being displaced at least partiall
