Abstract: A roof rail (10), which consists of a side rail (5) and support legs (7, 8). The support legs (6, 7) engage a roof channel (2), which is otherwise closed off by a cover strip (3). The support legs are connected to adaptors (8) at the bottom surface. The connection between the adaptors (8) and the vehicle roof (1) is established by means of threaded bolts (12) which are fastened to the adaptors (8) by means of a threaded portion (14) and to the vehicle roof (1) by means of a second threaded portion (16) with the use of threaded nuts. Each support leg (6, 7) is connected to each respective adaptor in such a manner that it can be loosened, while a bolt (17) with its threaded shaft (21) is screwed into the support leg (6, 7). Here, the bolt head (18) is seated in the adaptor (8) and includes a circular groove (23), one end of which is engaged by a threaded bolt (22) for the purpose of securing it in an axial direction, and where the bolt (22) is extended transversely to the bolt (17).
