ABSTRACT:
A signal generator comprising one or two horns and an electrically operated ir compressor is secured to a vehicle body, directly or indirectly, by a screw connection which includes a bolt with a hexagonal head received in a seat on a muff of each horn, the seat being formed by an open-ended channel accommodating the head and an adjacent narrower slot traversed by the shank of the bolt. This bolt may be inserted into a hole in the vehicle body or, in the case of two horns, may engage a strap bolted to that body; alternatively, such a strap with a pair of horns fastened thereto can be bolted to the associated air compressor which for this purpose has two diametrically opposite seats each similar to the one on the horn muff, one of these latter seats serving for the bolting of the compressor to the vehicle body.
