A raised boss (119) extends from the base of the cup-shaped member (111). The second casing member (121) is adapted to fit into the first casing member and to engage with the boss (119) in such a manner that the second member (121) is rotatable with respect to the first member (111). One end of a wire or cable (142) is secured to the second casing member and the wire or cable is wound around the periphery of the second member (121). The other end of the wire or cable (142) extends through a slot (145) in the side wall of the first casing member (111). A lock (152) is provided with which the other end of the wire or cable (142) is engageable and a coil spring (136) is arranged to act on the second casing member (121) to cause it to rotate with respect to the first casing member to draw the wire or cable into the first casing member by being wound around the periphery of the second casing member as the latter is rotated by the coil spring. Visual and audible alarm means are desirably provided which are arranged to be activated if the wire or cable is pulled or cut.</p> |
