To provide a highly reliable plug-in type pipe joint for easily visually confirming the status of a connecting pipe during insertion, and the state of the pipe after the insertion.

A connecting pipe inserting clearance 8 for receiving one end of the connecting pipe P is formed between the inner periphery of a transparent or semitransparent outer cylinder 3 and the outer periphery of an inner cylinder 2. An opaque part B is processed on the base end side of the outer cylinder 3. An insertion guide ring entering space 15 is formed between the inner periphery of the opaque part B and the outer periphery of the inner cylinder 2. An insertion guide ring 14 is incorporated into a joint body 1 so as to move toward the innermost part of the connecting pipe inserting clearance 8 while being pressed by one end of the connecting pipe P. The depth in the axial direction of the insertion guide ring entering space 15 is formed in the same length as the length in the axial direction of the insertion guide ring 14 or longer than that.
