The invention relates to a sleeve for connecting two pipe ends (1, 2) by adhesive injection into two annular spaces (3, 4) formed between the outer surfaces of the pipe ends (1, 2) and the inner surface of the sleeve, with a tubular basic body (5) which has a projection extending radially inwards from its inner surface, the side surfaces of which form a shoulder for the faces of the pipe ends (1, 2), with annular bodies (8) as centring and sealing rings having a surface (10) directed radially inwards to bear on the faces (7) of the basic body (5) and an axially extending surface (13) bearing on one of the lateral surfaces (11, 12) of the basic body (5), and with an annular shoulder (14, 15) running around the inner lateral surface (11) of the basic body (5) and to seal and centre the pipe ends (1, 2). The basic body (5), the annular bodies (8) and the annular shoulders (14, 15) are made by the injection moulding process. In order to make this more suitable for production in large numbers by the injection moulding process, the invention proposes that the basic body (5) and the annular shoulders (14, 15) consist of separate parts, each annular shoulder (14, 15) is a tubular centring and sealing ring bearing on the inner lateral surface (11) of the basic body (5) and the inner lateral surface (11) of the basic body (5) has no projections or recesses in the region of the projection (6), except said projection of course. |
