ABSTRACT:
The invention provides an improved reflection device comprising a tubular means enclosing a reflective element and arranged for mounting at desired level over a road surface at some distance from the road border. In the preferred embodiment, the tubular means has two open ends, and the reflective element has reflective material at both sides thereof and is arranged for being detachably inserted through a slot in the envelope wall of the tubular means. For eliminating or decreasing the risk of soiling the reflective element, said element is protected by the tubular means which has portions of substantial length in front of both sides of the reflective element. Preferably, each of said portions have a length of at least equal to half the internal maximum cross section dimension of the tubular means at the location of the reflective element. The reflective element is provided with a grip and is easily insertable and removable into and out from said slot. The slot is preferably converging towards the open end thereof. The tubular means can be moulded of plastic material integrally with an attachment flange for mounting said tubular means to a support rod.
