Coupling head for a rail-guided vehicle for forming a mechanical connection with a corresponding coupling head of the same design, wherein the coupling head extends along a coupling longitudinal axis and has: - two coupling claws (5, 6) which are arranged along a coupling longitudinal axis, offset with respect thereto, and form a coupling pocket; - a bolt mechanism which is arranged in the coupling pocket and has the purpose of mechanically connecting and disconnecting the coupling head and corresponding coupling head having - a bolt element for preventing the unintended release of the mechanical connection between the coupling head and a corresponding coupling head which is coupled to the coupling head, wherein the bolt element can be moved from a first position (locking position) in which release of the coupling head from the corresponding coupling head is prevented, into a second position in which release between the coupling head and the corresponding coupling head is made possible, and vice versa; - a bolt holder which is pivotably mounted on the coupling head and of which part a projects into the area of influence of a corresponding coupling and has the purpose of preventing the bolt element from moving out of the coupling pocket when the corresponding coupling head is present, wherein the bolt holder can be moved from a first position, free of interaction with the corresponding coupling head, into a second position which is characterized by interaction with the corresponding coupling head, and vice versa; - a locking and release mechanism for locking and unlocking the bolt element in the first position; characterized: in that an apparatus is provided for detecting the coupling state comprising a first device for detecting at least one variable which at least indirectly describes at least one position of the bolt holder, and a second device for detecting at least one variable which at least indirectly describes at least one position of the bolt element, wherein the first and second devices are arranged integrated on or in the coupling head. - two coupling claws (5, 6) which are arranged along a coupling longitudinal axis, offset with respect thereto, and form a coupling pocket;
