ABSTRACT:
A connecting device for conduits comprising a female connecting element having an axial bore opening at one end, and a male connecting element adapted to be inserted into the axial bore of the female connecting element. A first ball valve assembly has a housing adapted to be mounted at one end on the female connecting element and formed at the other end with a flat mating surface. In the housing, there is a spherical valve element having a diametrically extending through-hole. The mating surface of the housing is formed with an opening through which a part of the valve element projects. On the male connecting element, there is mounted a second ball valve assembly which is similar in structure to the first ball valve assembly except that the spherical valve element does not project beyond the mating surface but is formed with a part-spherical recess for receiving the projected portion of the valve element in the first ball valve assembly. The arrangements are effective to exclude air or other undesirable gas in connecting procedure.
