A housing for enabling coupling of light from a light source to an optical light guide. The housing allows for the optical light guide to rotate about its axis with respect to the housing and a light source while at the same time maintaining the optical coupling with the light source. Accordingly, it is desirable to couple light from a light source to an optical light guide, where the optical light guide is freely rotatable about its axis. This is obtained by a locking mechanism of the housing where the light source is arrangeable. The locking mechanism includes a circumferential structure adapted to receive at least one radial locking member of the optical light guide. The circumferential structure is configured such that the optical light guide is rotatable about its axis in the locking mechanism while maintaining a spatial relationship between the end portion of the optical light guide and the light source.
