A pipe coupling (1) for repairing damaged points and/or for connecting in one or more branched portions of a pipeline has a cylindrical housing (2), the two ends of which are formed as hexagonal parts and the interior of which is a continuous passage (10) which, in the axial direction, adjoins initially widened bevels (11, 12) and then has an internal thread (13 and 14, respectively) for screwing in set screws (17 and 18, respectively) which consist of a deformable material which is provided for radial compression in conjunction with the tightening of the screws to couple together and arrest abutting pipe ends. According to the invention there is arranged, in the continuous passage (23) of one set screw (18), a positioning sleeve (38) which, after insertion of one pipe end into the other set screw (17) and main part of the passage (10) of the housing, forms an insertion-stopping means for said one pipe end and is guided in the radial direction for flush abutting or exposing with respect to the other pipe end and, thereafter, forms a stationary coupling part, in relation to which the housing is displaced, along with the two inserted set screws, before the latter are tightened, into a central position over the sleeve (38) which is arrested in this position with respect to the housing (2) by a bead (43) engaging into an inner groove (19) in the housing, whereupon the two set screws (17, 18) are provided for tightening. <IMAGE> |
