Ring, has front and rear loops articulated in rotation around axis which is in loop with greater thickness, by pin projecting from inner lateral side of rear loop and engaging in front loop hole
Ring, has front and rear loops articulated in rotation around axis which is in loop with greater thickness, by pin projecting from inner lateral side of rear loop and engaging in front loop hole
The ring has front and rear loops (1, 2) movable with respect to each other between assembled and open positions in which the loops are joined and spaced from each other, respectively. The loops are articulated in rotation around an axis which is in the loop having greater thickness, by a cylindrical pin (6) which projects from an inner lateral side (7) of the loop (2) and engages in a hole (8) of the loop (1).
