Abstract: To adapt a new attachment for an electric torch or flashlight of the kind having a generally cylindrical barrel so that it can be magnetically attached to a magnetic surface, an attachment is provided composed of a body shell which is a resilient partial sleeve with one or more magnets secured to it. The shell may be conveniently made from a plastic material tapering in thickness in opposite circumferential directions towards its axially extending edges. The shell snaps over the barrel of the torch and may have an opening for accommodating the switch and the switch housing so as to provide access to the switch and allow precise location of and prevent movement of the shell along the barrel.
