Abstract: A single-piece hanger is disclosed. The hanger comprises a single piece of resilient metal formed in an generally "J" shape and defining opposing legs, joined at a closed end of the J by a bend from which the opposing legs extend at angles from one-another. Retaining teeth adjacent the closed end are defined on the opposing legs. Handles for gripping the hanger are also on each opposing leg. The opposing handles are gripped to compress the legs together. After the legs are compressed the closed end and the retaining teeth are placed within a work piece such as tubing or piping. The handles are released permitting the resilient hanger to return the legs from a closed position toward an open position; resiliently carrying the retaining teeth into gripping contact with the work piece. Means are provided for maintaining the closed end intact against distorting forces applied through compressing the opposing legs.
