Coupling device

A coupling device comprised of two connector block parts which can be coupled to each other (2, 4) with a plurality of receivers for connector parts (10), which connector parts are arranged corresponding with each other and can be connected to each other, characterized in that a facilitating device is provided for supporting the coupling process, having on the one connector block part (2) a pivotable handle (16) with at least one guide slot (30), a facilitating device is provided for supporting the coupling process, having a pivotable handle with at least one guide slot on the one connector block part, into which guide slot at least one guide part (32) of the other connector block part (4) engages such that when the handle (16) is pivoted the guide slot (30) applies a force to the guide part (2, 4) in question in such a way that the connector block parts (2, 4) are moved toward each other for a coupling process.
