Multi-use fixing knob with double housing for the assembly of two rods forming an angle between them. It consists of two superimposed stirrups (1), assembled one to the other, and each one containing a housing (2) for the reception of one of the two bars and some strapping (6,28) of the bar in the housing. The two stirrups (1) can be assembled by pivoting one in relation to the other around an axis (9) and can be associated with a part (18) which allows their clamping in whatever angular position. It is characterised that the clamping part (18) is controlled at the time by the two bars and by the strapping (6,28) in such a way that the clamping of the two stirrups (1), one in relation to the other can be obtained exclusively when the two bars are strapped in their housings (2). |
