The ohjscl. of my invention to provide a device to placed in a. service circuit, preferably cicsc to pole or other support and suspended in tho lino of onc of the elec- -tric conductors of on clcctric circuii suppiyingg" cloc trinity to a.v consumer, so that the current- EHW' he turned or on at any time entering;- consinncfs premises or disturbing or disronnciting any wires.

In the drawings and 11 indicate ii pair of metallic members each of which is prcfcrably provided its outer end with on eye 12 through \v lCll thc conduct r13 may he passed. the conductor 13 is preferably insulated I consider it advisable, in order to insure hettcr contact than ivould he possible by merely having: the (JOYJKlUCtOl' at oyc 12, to provide each of lk-f niemhors IO and 1} with a binding post 14.- lo receive the. mid of the adjacent, sonductor 13.

of said members, at its inner end, with one or more transversely extending hooks or lingers 2i which lie within the block 20 and resist the pull of conductors 13.

In nm'nuliiclure, screw 1-5 is moved into si'igsgenient Wllil seat 16 and the ports are i then 6I'llli\;(l(i5 4i in 8- plastic which will harden. r

(Bl course the block 20 may be formed in any other desirable manner without departingfrom my invention.

In order to prevent tampering with screw 15 I prefer to so form it as to require a special key for its manipulation sndof course any special form m be adopted. In the drawings I have shown screw 15 provided, at its outer end, inside sleeve 17, with a cross pin adapted to he received-in a slot 23 of a socket key 24.

In use she device! is connected into one side of a circuit at any desired point, for instance at the pole supporting the s rloin feeder Wires at the point where the service circuit is taken oli, and by turning}; screw 15 into or out oi. seat 343 the service circuit may be established or broken without entering the premises of obs consumer. The members l0 and 11 being embedded in the block 20 at. the point of possible contact, (1'.

screw l5 and scal 16') these parts are thoroughlv protected from the weather and there is no d anger of short circuiting with moisture.
