A joint for connecting a corrugated pipe to another member includes a cylindrical body having an annular step portion formed in its inner part and adapted to be brought into contact with a front end of a corrugated pipe; a chuck having an annular body which includes a forward end part of an inner diameter substantially equal to or slightly smaller than an outer diameter of the corrugated pipe and which exhibits elasticity by which the chuck can contract and expand in radially inner and outer directions, an engaging portion formed on an inner periphery of its forward end part for engaging an outer periphery of the corrugated pipe, and a locking portion formed on an inner periphery of its rearward end part, the chuck being engaged with the outer periphery of the corrugated pipe in the cylindrical body so as to be capable of moving the corrugated pipe into the cylindrical body integrally with the chuck; and a push cylinder having a counterpart locking portion formed on an outer periphery of its forward end part and adapted to be locked to the locking portion formed on the rearward end part of the chuck, the push cylinder being slidably fitted to an inner periphery of an end portion of the cylindrical body, the push cylinder being for pushing the chuck into the cylindrical body when the push cylinder is advanced.
