The invention relates to a connection device (100, 101, 102, 103) for a solar module (400), the connection device (100, 101, 102, 103) having a housing (110, 111, 112, 113) and a contacting means (180), arranged in the housing (110, 111, 112, 113), for contacting a contact element (430) of the solar module (400). The connection device (100, 101, 102, 103) is distinguished by a blind mating connector (120, 150) arranged on the housing (110, 111, 112, 113) without an electrical connection to the contacting means (180), onto which connector a plug-and-socket connector (220, 250) can be plugged. The invention furthermore relates to a solar module with such a connection device (100, 101, 102, 103).
