Narrative:
During preflight of my oxygen system, I found the oxygen hose disconnected. I plugged it in and the mask check worked ok. I noticed in the logbook where maintenance had replaced the oxygen mask. I figured that it had been installed improperly. The aircraft had flown about 3 times since then and I didn't write it up because I didn't want to cause those 3 pilots grief on any follow-up. I just saw a message on an oxygen hose that was disconnected. I called pilot union safety and they suggested I submit a report.
