ABSTRACT:
To restrict a fitting length of an inserting side tubular member such as a corrugate tube into a receiving side tubular member having a flexible portion such as a rubber boot when the inserting and receiving side tubular members are connected. Projections 16 are formed on the inner surface of a fitting end portion 13. When a corrugate tube 20 is fitted into the fitting end portion 13, a leading end 20A thereof comes into contact with the projections 16, thereby restricting any further insertion of the corrugate tube 20. This prevents the entry of the corrugate tube 20 into the flexible portion 12. Accordingly, there is no likelihood that the smooth deformation of the flexible portion 12 is hindered by the entry of the corrugate tube 20 into the flexible portion 12. Further, since there is no need for a consideration as to an excessive insertion of the corrugate tube 20, the connection can easily be performed.
