A coupler plug, configured for a planar lambda probe, for example, is described as including a housing having a base element and a cover element, as well as including electrical components configured to be inserted arid fixed in the housing, and an adjusting element for a probe, such as, for example, a planar broadband lambda probe, which is mounted in the coupler plug or outside the coupler plug, via a further contact element. The cover element is attachable over the adjusting element and includes a primary locking mechanism for arranging the cover element in a first latching position and a secondary locking mechanism for arranging the cover element in a final position, which cooperates with the cover element. To seal off the housing, at least from dirt and dust in either the first or final latching positions, a seal is mounted on the cover element, the seal having sealing lips that point away from the cover element and bring about a sealing connection with the housing in the first latching position of the cover element.
