A plumbing strap is fastened to a building. A tubular insert is placed through a hole in a strap with posts on the tubular insert aligning with
cut-outs in the strap to
restrict rotation of the tubular insert relative to the strap. A
flange on one end of the tubular insert abuts the strap to
restrict longitudinal motion of the tubular insert. Latches on the tubular insert extend through the hole in the strap to engage the side of the strap opposite the
flange and further
restrict longitudinal movement of the tubular insert. A collar is placed over the tubular insert and a
pipe extends through the tubular insert and collar. The tubular insert has a base adjacent the
flange and a skirt distal from the flange. Longitudinal slits in the base and skirt define resilient members in the base and in the skirt that extend in opposing directions, but that can move inward. The collar screws onto the tubular insert causing abutting surfaces on the collar and on the resilient members to force the resilient members inward to grip the
pipe and restrain longitudinal and rotational movement of the
pipe relative to the tubular insert and strap.
