The invention relates to a securing device (1) for securing a luminaire (1) on a mast top, comprising an attachment (3) and a connection element (4) as two main elements. The attachment (3) has a cylinder portion (31) for placing on a mast top, said cylinder portion extending in a longitudinal direction over a cylinder length. The connection element (4) is designed for connecting the luminaire (2) and is connected to the attachment (3) via an articulated connection. The securing device (1) comprises two retaining elements (5, 6), each of which has a disk (50, 60) and a guide portion (52, 62) which runs away from the disk (50, 60) over a guide portion length. The guide portion (52, 62) has a constant cross-section at least along some sections, and the disk (50, 60) has a toothing structure (51, 61) on one of the disk faces. A first of the two main elements (3, 4) has a guide channel (7) for receiving the guide portions (52, 62) of the two retaining elements (5, 6), and the second of the two main elements (3, 4) has two latching surfaces (40). The guide channel (7) runs in a transversal direction and has a cross-section which corresponds to the guide cross-section, and the retaining elements (5, 6) can be arranged in the guide channel (7) and can be moved in the transversal direction. The latching surfaces (40) are mutually spaced in the transversal direction, and each latching surface has a latching structure (41) which corresponds to the toothing structure (51, 61) of the disk faces. The first main element (3, 4) comprises a moving element (9) which interacts with the retaining elements (5, 6) in an assembly position of the securing device (1) and which is designed to move the retaining elements (5, 6) in the transversal direction in the guide channel (7) by applying a force. The retaining elements (5, 6) in the guide channel (7) and the latching surfaces (40) are arranged relative to one another such that the toothing structures (51, 61) of the retaining elements (5, 6) can be pressed against the latching surfaces (40) of the second main element (3, 4) by means of the moving element (9). |
