The figure illustrates a detailed view of the fixing system. The same can highlight the following:
a) Structure of hinged bars and sliders: The set of joint and sliders gives the system a roto-translational movement in order to open and close the clamps.
b) Screw: The separation between the two clamps, distance "d", is regulated by turning the screw, in order to hold tubes of different diameters.
c) Positive mechanical action interlocking device: This mechanism ensures that once the tube is gripped, the clamps can not be opened accidentally. In order to release the pipe, there is a button that must be manually operated
