A method is described for fastening coupling means to respective ends (25,26) of pipes (10, 12) that are to be joined together, comprising a pair of mutually axially telescopic conical casings (18,22) that are inserted, one on each pipe end, as the conical casing pair are mutually pushed together with the help of respective tightening bodies (14, 16) so that the radially outer casing (18) squeezes the inner casing (22) into a fastening against the surface of the pipe (10, 12) and joins the pipe ends together, so that a tight joining together is achieved between the ends (25,26) of the pipes (10, 12) and it is characterised in that an inner conical casing (22) is used which is divided into a number of sections of axially directed slits (30) through the wall of the casing, said slits (30) contribute to the inner casing being able to be forced radially inwards during the simultaneous closing of the slits (30) and so that the inside of the inner conical casing is forced into a fastening against the surface of the pipe during the mutual pushing together of the casings. A coupling construction and an application of this are also described. |
