Zusammenfassung:	Apparatus for freezing a medium flowing through a pipe in a nuclear installation comprises a tongs-like head with two jaws (22,23) which can be clamped round the pipe and which are joined together by a hinge (24). A chamber is formed in each of the jaws (22,23) and can be supplied, through connections (29), with a liquid refrigerant which flows out through a plurality of radial holes (27) onto the surface of the pipe to be frozen and evaporates thereby cooling the pipe and freezing the medium flowing through the pipe. The free ends of the jaws (22,23) preferably taper to assist engagement of the pipe. A motor may be provided to close the jaws (22,23).
