■. . sleeve

The invention relates to sleeves, in particular end sleeves for attachment to the ends yo: a pipes, conduits or Metal hoses β - "" "

Sockets for fastening to the ends of pipes or lines, both for plugging on and for screwing on, are already known. These known constructions often have a disadvantage that their outer end has a relatively sharp edge is present ^ whereby, for example, lines that are housed in the pipe or the ^ line can be easily damaged.

The disadvantages of these known constructions are avoided according to the invention by the fact that the sleeve has at its front end part a mouthpiece part which is flanged over in such a way that it encompasses the part of the metal pipe on both sides.

If the end sleeve opens. a. Metal hose is to be screwed, it ^is% expedient if the end sleeve also · comprises a metal pipe section, wherein preference the turns of the metal tube piece between the walls of Mundstüekteiles ~ are axially tightly pushed together - ^ is mechanically reinforced whereby the mouthpiece>:;; ■ "· ■■: '/":. --_
