2. In an electric plug connecter, the combination of a body member provided withr an aperture, a pair of contact prongs having inner end portions enclosed in said body and outer end portions projecting from said aperture and beyond the adjacent end oi said body member. a spacer member interlocked with said body for maintaining said contact prongs in spaced relation and serving to close the end of said aperture from which said prongs project, and a pair of electric current conductors connected respectively to said contact prongs within said body portion, the body and spacer members being relatively distortable to permit assembly of the body and spacer.

3. An electric plug connecter comprising a main body having a recess therein, an auxiliary member interlocked therewith, one of said members being formed of resilient material so as to be capable oi' being distorted for permitting interlocking thereof with the other member, and a contact prong disposed in the recess in said body member and having a portion engaging said auxiliary body member, whereby the contact prong' is positioned in said body.

4. An electric plug connecter, comprising a main body member having a recess therein, an auxiliary body member interlocked therewith, one of said members being formed of resilient material so as to be capable of being distorted 'for permitting interlocking thereof with the other member, and a terminal disposed in the recess in said main body member and provided with a portion engaging said auxiliary member, whereby the terminal is retained in said aperture.

5. An electric plug connecter, comprising a main body member having a recess therein, an auxiliary body member interlocked therewith, one of said members being formed of resilient material so as to be capable of being distorted for permitting interlocking of said members, aA

terminal disposed in said recess, and a contact member connected to said terminal, said terminal and contact member being provided with means engaging said auxiliary member and thereby maintained in operative position relative to said main body member.

6. An attachment plug cap comprising a base made of a soft, flexible, elastic rubber like material having a shallow chamber therein and a circumferential groove adjacent to the floor of said chamber, a removable insulating disk in said groove, outwardly and inwardly extending extending ends of said pins seating in cavities in' said body, all of said parts being held in assembled relation by the inherent elastic properties of said body.

8. A connecter cap comprising a body made of a soft, exible, elastic, rubber like material having a chamber therein, an'insulating connecter pin retainer removably held in said chamber by the inherent properties of the base, connecter pins supported in cavities in said base and extending thru said retainer, and shoulders on said pins and resting against said retainer to prevent longitudinal movement.

9. An attachment plug cap comprising a base made of a soft, flexible, elastic, rubber like ma- -terial having an open chamber formed therein,

said.chamber having a circumferential groove formed in the wall thereof, a disk of insulating material, the wall of said chamber being distortable to permit insertion of said disk into said groove, a pluralityof one-piece-combined plug jack and wiring terminal members extending through said disk in spaced relationship to each other and having parts abutting said disk, the wiring terminal portions of said members extending rearwardly of-said disk for concealment thereof within said chamber, and the plug jack portions of said members extending forwardly from said disk beyond the end of said base.

l0. An attachment plug cap comprising a base made of soft, rubber-like material having an open chamber in one end and an axial cord passage communicating with said chamber, plug-jacks located in said chamber and seated in direct contact with said base, and means to secure said plug-jacks to said base, said means comprising a relatively thin and relatively rigid disk-like member of insulating material supported within said base transversely of the latter, said plug jacks being associated with said disk-like member to be spaced thereby.

1l. In an attachment plug cap, the combination with a base comprising a molded soft, rubberlike body and a relatively thin and relatively rigid disk-like member of insulating material, said body having an axial cord passage and an open end chamber communicating with said passage and said disk-like member being supported within said body transversely of the latten-of a 'plurality of one-piece combined plug-jack and wiring terminal members located in said chamber in said body and seated in direct contact with said body,said plug-jack members and said disklike member having mechanical connections whereby the former are anchored and spaced by the latter, the aforedeiined construction enabling attachment and wiring of said plug-jack members subsequent to molding of said body l 12. An attachment plug cap comprising contact prongs and a supporting base therefor into which conductors may be led in one direction for attachment to said contact prongs, said contact prongs having integral terminal parts extending into said base in an opposite direction for enclosure of said terminal parts by said base whereby at least a partially unassembled relation of said base and contact prongs is a prerequisite of f FRANCIS C.
