Provided is a resin-made tube joint that can be reconnected easily and reliably with a tube after the connected tube has been removed, and in which sealability between a joint body and a sleeve can be maintained favorably both when the tube is connected for the first time or when the tube is reconnected. By pressing an insertion part 27 of a sleeve into a groove part 20 of a joint body, a seal part 31 that seals the inner circumferential surface of the insertion part and the outer circumferential surface of an inner cylinder part 13 is formed. When the insertion part is pressed into the groove part, a space 33 is formed between a protruding end 30 of the insertion part and a body cylinder part 11 which is located on the opposite side, in the axial direction, from the opening section of the groove part. In a cross section including the axial center of the inner cylinder part, after the completion of the pressing of the insertion part into the groove part, a region 35, within the outer circumferential surface of the inner cylinder part, that faces said space forms a predetermined angle ranging from 5° to 15° with respect to the axial center of the inner cylinder part. |
