Abstract: The invention proposes a connecting plug device for electrical equipment and more particularly rows of solenoid valves in the case of which on one side of a housing there is a contact arrangement for cooperation with an arrangement of mating contacts on the item of electrical equipment. On two further sides of the housing there is a respective set of electrical plug connecting contacts. One plug connecting contact is connected with one plug contact of the contact arrangement and at least one further plug connecting contact is connected with the corresponding opposite plug connecting contact and with a further plug contact electrical, while the remaining plug connecting contacts are connected with the plug connecting contacts arranged offset in relation to the respective opposite plug connecting contacts.
