Abstract

1410769 Pipe couplings VISCOSE DEVELOPMENT CO Ltd 27 Nov 1972 [30 Nov 1971] 55521/71 Heading F2G In order to prevent a pipe union from being tampered with, a sleeve 5 is shrunk tightly over e.g. a gas pipe union 3, having a projection 4 fixed to one pipe 2, so that the union cannot be turned relatively to the one pipe without irreversibly deforming the sleeve. Preferably the sleeve is made of heat shrinkable P.V.C.
