The present invention relates to a connector pipe, which is adapted to permit connection of a feed pipe (6) for waste water to the connector pipe (5) such that said feed pipe and said connector pipe can move in axial direction relative to each other without gliding aport, and to permit connection of the connector pipe to a side inlet (4) to a floor drain (1). In order to provide a connector pipe which permits the pipes connected with each other, i.e. the feed pipe for waste water and the connector pipe, to move relative to each other wityout deteriorating or disturbing the sealing therebetween and which also defines a liquid seal as well as durable connection between the connector pipe and the side inlet to the floor drain, the connector pipe (5) consists of two members (5a and 5b), one of these members (5a) includes a pipe socket (8) with external threads (9) and an end flange (10), whereby the pipe socket is insertable through a side inlet opening (4a) in the floor drain (1) with the end flange disposed in said floor drain, the other of said members (5b) comprises a pipe portion (11) with internal threads (12), whereby this latter member (5b) can be screwed onto the first member (5a) until these members are clamped onto the floor drain (1), and said other or second member (5b) also comprises a connecting portion (15) into which the feed pipe (6) can be inserted, whereby said connecting portion (15), in a manner known per se, tapers in the direction of withdrawal (B) of the feed pipe (6) and includes a ring (16) of elastic material positioned therein in an inner position in the widest part (15a) of said connecting portion and permitting in this position insertion of said feed pipe (6) into the ring while it at the same time engages the feed pipe (6) inserted therein in such a way that said ring is drawn towards an outer position when said feed pipe is moved in its direction of withdrawal (B) and whereby the connecting portion (15) due to its tapering shape causes deformation of the ring (16) when said ring is moved towards its outer position, such that said ring is brought to engage and take hold of the feed pipe (6) with an increasingly stronger force, and the feed pipe (6) can be inserted so far into the ring (16) that an end portion (6a) of said feed pipe situated within said ring remains within said ring when the ring has been drawn to its outer position. |
