Abstract

Joint for connecting pipes composed of a body provided at least at an end with an outer thread; a cylindrical seat for inserting the pipe inside said body; a ring nut intended to be screwed at the end of said body on the thread, said ring nut being provided with an inner conical surface; at least a clamping ring with an outer shell surface that is at least partially conical and intended to cooperate with the inner conical surface of said ring nut and which ring internally has teeth intended to grip the end of the pipe inserted in the joint and said ring having the possibility of being tightened by means of a radial restriction caused by the ring nut being screwed on the body; at least a seal between the cylindrical seat of the body and the outer wall of the pipe, having such a shape that under the resting condition it allows the pipe to be easily inserted or taken out. In such joint the clamping ring has an intrinsic elastic force for firmly maintaining a condition whereinits inner diameter is slightly greater than the outer diameter of the pipe, so that the latter can be inserted by an axial sliding action without any impediments in the clamping ring, and said clamping ring can be elastically deformed narrowing the inner port delimited by the ring, against the action of said elastic force in a condition with the diameter reduced with respect to the diameter in its resting condition, at such an extent that teeth of the ring grip the wall of the pipe by firmly clamping it inside the joint, said reduction being generated by the action of the conical surface of the ring nut on the conical surface of the clamping ring during the screwing action.
