A device for the detachable securing of a cloth (7) or the like to a boom (1, 8) or the like. Extending between two free longitudinal edges of a base profile (1) of the boom are two profiles, preferably made of aluminium, namely a joint profile (3) and a lock profile (5), the first articulated to one longitudinal edge of the base profile and the latter to the former, the lock profile being able to be brought into engagement with the base profile at its second longitudinal edge while gripping the cloth. Due to the inherent springing of the profiles, the joint between the joint and lock profiles can snap with a locking action over a neutral line. The lock profile is extended backwards and downwards to form a complementary part (8) of the boom, serving as a handle member. |
