Abstract
A pipe fitting includes a slider disposed in an insertion hole of a main body so as to be axially moved and includes a pressed portion which a falling-off preventing flange of a pipe abuts so that the slider is pressed axially when the pipe is inserted into the insertion hole. A fitting checker includes a pair of spreading legs having respective claws, the fitting checker being detachably attached to the main body so that the legs hold the main body. The claws engage the body and the slider so that the fitting checker is not allowed to be detached from the body when the legs are closed. The legs are spread so as to release the claws from engagement with the body and the slider so that the fitting checker is allowed to be detached from the body. Releasing protrusions are formed to protrude from inside portions of the legs of the fitting checker, the releasing protrusions being pressed so that the legs are elastically deformed in respective opening directions. A pressing portion is formed on the slider so as to press the disengaging protrusions of the fitting checker to spread the legs of the latter when the pipe is inserted into the insertion hole to assume a normal fitting position so that the slider is displaced to a normal thrust position.
