Hinged connection device of two tubular components

A hinged connection device includes first and second tubular components around a main axis which respectively include a first male hinge member provided with an end head shaped as a spherical segment and a second female hinge member provided with a complementary seat receiving movably inside the end head of the first member. The first member is configured to be housed at least partially inside the first component and to be assembled to the second component throughout the second member. The second member is configured to be mounted around the second component and assembled to the first component over the first member such that the two tubular components are assembled together by the reciprocal intersection of the two hinge members.
