Abstract

In order to avoid the specific disadvantages of screwed and welded connections of pipe ends, a plug connection is proposed in which both pipe ends (1, 2) have a collar-like expansion, provided with a bulged section (4), the sections (4) being surrounded externally by a clamping body (14) whose design is matched to these sections with a view to producing a positive closure. Inside the collar-like expansion there is a metallic core pipe (6) which externally - overlapping its end face ends - carries annular sealing elements (7) which are provided in the region of their end face ends which rest on one another with retaining pockets for a curable plastic which is partially forced out of these pockets when external pressure is exerted by means of the clamping body (14) and at the same time fills the central annular space (15) between the bulged sections (4) on the one hand and the clamping body (14) on the other hand. This results in a plug connection which has smooth walls on the inner side, can easily be assembled and is protected against axial thrust in a reliable manner. <IMAGE>
