Abstract: A spring support particularly intended for supporting pipes in installations where the pipes are liable to move laterally while in use, as for example in the case of pipes through which steam is conveyed, has provision for locking its compression spring means against movement relative to a body of the spring support in a plurality of positions longitudinally of the axis of operating movement of the spring. Preferably the spring means can be locked in an infinite number of positions within the operating range of its longitudinal movement. Thus if for any reason it is desired to resist movement for a while of a pipe which is supported by the spring support during use, the spring means can be readily locked against movement in the operative position it was occupying, without first having to move the spring means to another position before the spring means may be locked.
