In the body of a pipe support a piston supported on a compression spring is movable relative to the body. A turnbuckle suspended from the piston passes down out of the body and, in use, is connected to a pipe to be supported. The body and the piston have adjacent each other oppositely inclined slots. The piston may be clamped to the body by a lock nut and a lock washer which are interconnected through registering portions of the slots by a bolt. The bolt can be slackened off to allow the nut and washer to slide in the slots so that the piston can move freely in the body. The oppositely inclined slots allow the piston to be clamped to the body at any position within its range of movement.
