The invention provides a bite type pipe connection structure, valve, bite type pipe joint, and freezing device. The bite type pipe connection structure is used for connection to a large diameter piping which is previously set as a standard specification. The bite type pipe connection structure has: a spacer (71) which is used for connecting a small diameter piping (P3) as an insertion port adjusting means which adjusts a gap between the insertion port (16) and the small diameter piping (P3); a stage part (73) as a stage part for a small diameter for regulating the position of the tip of the small diameter piping (P3); and an insertion hole adjustment means which bridges a gap between the insertion hole for a large diameter of a ferule for the large diameter and the small diameter piping (P3) for adjusting the insertion hole. The insertion hole adjustment means is obtained by changing the ferule (3) for the large diameter to a ferule for a small diameter (6). This makes it possible to connect the small diameter piping (P3) with a joint main body (1) attached to a device.
