A coupling arrangement for coupling members as a gear change coupling in a gear mechanism unit includes a first member and a second member. The first member has a coupling toothing system. At least one locking body arrangement is mounted pivotably on the second member. The locking body arrangement can be pivoted into a coupling position, in the case of which a driving section on the locking body arrangement engages into the coupling toothing system. The locking body arrangement can be pivoted into a release position, in the case of which the driving section of the locking body arrangement does not engage into the coupling toothing system. The locking body arrangement has a locking body carrier which is mounted pivotably on the second member, and has a locking body member which is mounted pivotably on the locking body carrier and on which the driving section is configured.
