A device for connecting a first optical component to a second optical component, particularly for connecting the lamp housing of a spotlight to a lamp adapter. The device includes a connecting ring which has a first region which rotatably secures the connecting ring to the first optical component, and a second region which is axially distanced from the first region and enables the connecting ring to be connected to the second optical component. The second region includes coupling means, which engage with corresponding coupling means of the second optical component by rotating the connecting ring. The invention enables two optical components to be connected in a fast, simple manner.
