ABSTRACT:
The present invention relates to a fast connection with radially acting bolt-locking having a groove in the male element and a bolt in the female element that can receive an axial displacement and whose rear flank when locking engages in the groove of the male element, the bolt being urged into locking by a spring. According to the invention, at least two balls mounted with free radial play in the body of the female element are interposed between at least two points on the perimeter of the bolt symmetrical to the axis of thrust of the spring and a longitudinal ramp embodied on the inner surface of a sliding ring. The invention is applicable to fast connections for piping.
