In order to improve the fitting and especially the securing of a connection pipe (21) in the branch aperture (13) of a conduit (1), a spacer ring takes the form of a locating ring (3) which is secured to the body (21) of the connection pipe by securing components (22, 27, 35) in such a way that, when the connection pipe body (21) is inserted into the branch aperture (13), the sealing component (4, 5) fitted in the sealing chamber (24, 25) is placed in the correct position in relation to a wall surface (14) of the branch aperture. In at least one of the sealing chambers (25) facing the inner surface (12) of the conduit (1) is fitted an annular seal (5) having at least one sealing lipped ring projecting beyond the outer contour of said sealing chamber (25). At least one of the sealing chambers (24) facing the outer surface (11) of the conduit (1) is filled with a flexible sealing compound (4) in such a way that a gap (1424) extending from the sealing chamber (24) to the wall surface (14) of the branch aperture (13) is bridged and sealed.
