Abstract

Splice device for rigid and semi-rigid tubes, of any synthetic thermoplastic material, or metal, comprising a sleeve provided with at least one fitting mouth of the end of a pipe to be joined, as well as mechanical fastening elements of the tube or tubes and spliced hermetic seal of the splice, characterized in that said sleeve is divided into two coaxial parts capable of being coupled together by mutual screwing, and is provided internally, from its fitting mouth, or each of its socket mouths, diameter slightly larger than that of the end of the corresponding tube to be connected, of a frustoconical chamber determined inside the anterior part 2 of the sleeve by a conical surface, taper directed towards said mouth and bounded at the end opposite it by a first step circumference) practiced on the back piece of the sleeve and, from this first step, a cylindrical portion coaxial with said mouth, fitting, of diameter substantially equal to that of the latter and also finished by a second circumferential step, the mechanical clamping members of the respective spliced and sealing tube of the fitting being housed in said truncated conical chamber of the sleeve and being made thereof so as to allow the plug, axially, the end of the pipe to be spliced until this end abuts against said second circumferential step disposed at the end of said cylindrical portion, and the sealing member is applied against the first circumferential step that internally limits said frusto-conical chamber of the sleeve sufficient to achieve a tight coupling with making a slight screwing in the sense of bringing together both parts of the sleeve, while the plug of the internally spliced tube can be easily made by slightly separating the two pieces that with they place the cuff.
