(01. while Thisinvention relates to connectors and more particularly it relates to a device for anchoring an element such asan-el'eotric conduit, an electric conductor or the like to a support such as an outletloo-X or junction box or the like.

' 'One of the object's-ofthisihvention is-tho provision of a connector which maybe easily and securely fastened to the supportwiththe connect'ed element gripped by the device,- whereby it isseourely anchored to the support;

Another object" is to provi de'a twopart =conneetor with the body: portion of one part disposed at one side-of the wall of the support and the other; part disposed onthe opposite side of" the wall, with-the two par-ts- -pavtly gripping the-wall and one or-the parts t'ig ht'ly'gripping the con neot'edelement.

Another: object: is to provide a two-part conne'ctor, one part of which is formed" with jaws for engaging the element connected to the support, and the other part having a thnead'ed comnectionwith the-first part whereby whenthe two parts are screwed up tightly with the wall of the: suppont interposed between themthejaw-s are swung; into gripping engagement: with-the con-- nected'elementi Other objects and: advantages: will appear "in the course oi "thiSe specification; 'andw wi'thoall. of; said objects: and advantages in View; this inverttion; consistsyin the severalxnovel fceatures "hereinarter fullyz set:f orthand: claimed:

In the form of the invention illustrated in Fig. 5, the parts are substantially the same as those of the corresponding parts seen in Figs. 1 to 4, except that the corners formed between the internal walls of the nipple portion and the ,end faces of the segments are pointed or sharpened as at 22, and they cut into .the connected element when the nut is screwed up tightly.

In the form of the invention illustrated in Figs. 6 and 7, the construction of the body portion |a of the connector is substantially the same as that shown in Figs. 1 to 4 inclusive, ex-

cept that the tapered faces are fiat, and a rubber or other elastic filler 23 is filled in the slots between the segments and in the recess at the back of the body portion and the bore through the nipple and body portion is lined with similar material, thereby providing a seal between the support and connector. When the clamping nut is. applied, this resilient or plastic material will be deformed by the pressure exerted to close or fill in all the holes or dents, whereby moisture, gas orair escape. .In the case where both units may be metallic as well as the conduit, this resilient or plastic element may be made of an electrical insulating material which will further serve the purpose of becomingan electrical insulator. When this resilient material is introduced it will permit reasonable movement of the conductor, cable, conduit or other element due to expansion, contraction or other vibration without affecting the seal.

The body portion of the connector may be formed of metal or other resilient material such as plastic. v,

The use of this device is not necessarily restricted to the use of, or application to, the anchoring electrical conductors, but may be applied to many other uses such as holding or clamping of hollow pipes for fuel lines, waterlines, gas lines, etc., through the holding of rods, bars or shafts, clamp ing of cords cables or ropes, or for holding any device in locked or anchored location.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence, I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described or uses mentioned.
