A pipe hanger includes generally U-shaped upper and lower hanger parts, and a locking bolt for interconnecting the upper and lower part. The lower hanger part has a saddle portion for supporting a pipe. One of the arms of the upper hanger part has a hook formed on a lower end. The corresponding arm of the lower hanger part has an aperture that is arranged over the hook. The same arm of the lower hanger part has at its end a tilt limiting abutment. In an open state of the pipe hanger the lower hanger part can be suspended from the hook and is allowed to swivel until the tilt limiting abutment abuts the corresponding arm of the upper hanger part. The other arm of the lower hanger part has a bore for the locking bolt to lock the lower hanger part and upper hanger part in the closed position.
