What is claimed is: 1. A connector for introducing an armored cable into a wiring box, comprising: a hollow body; a first biasing component coupled to the hollow body and operative to press against an inner face of a wall of the wiring box in an installed state of the connector, the first biasing component being configured with a plurality of angularly spaced-apart lugs extending transversely to a longitudinal axis of the hollow body through a front end thereof and each operative to exert the force against the inner face of the wall of the wiring box in the installed state of the connector; and a second biasing component coupled to the body at a distance from the first biasing component and operative to press against an outer face of the wall in the installed state of the connector, the first and second biasing components generating respective oppositely-directed forces directed against the wall of the wiring box and minimizing voluntary disengagement of the connector from the wiring box. 2. The connector of claim 1, wherein the lugs each have a plurality of leaves coupled to one another to one another so as to exert the force against the inner face of the wall. 3. The connector of claim 2, wherein the plurality of leaves of each of the lugs are configured to define a substantially triangularly-shaped cross-section. 4. The connector of claim 1, wherein the first biasing component is fixed to the front end of the hollow body. 5. The connector of claim 1, further comprising at least one elongated spring extending within the hollow body between front and a rear ends of the hollow body and integrally provided with the first biasing component, the first biasing component including a front lug on a front end of the spring and extending transversely to a longitudinal axis of the hollow body through the front end thereof so as to terminate at a radial distance from the body and press against the inner face of the wall in the installed state of the connector, the front lug being biased radially outwards by the armored cable inserted through the hollow body, wherein the inserted armored cable and the front lug are in continuous contact with one another for providing grounding of the armored cable. 6. The connector of claims 5, further comprising a second elongated spring extending through the hollow body at a distance from the one spring and having a respective front lug, the respective front lug extending transversely to the longitudinal axis of the hollow body through the front end of the body and terminating at an angular distance from the front lug of the one spring, the first biasing components of the respective one and second springs being uniformly configured to provide multiple spaced contact points with the inner face of the wall of the wiring box. 7. The connector of claim 6, wherein the one and second elongated springs each have an intermediate pair of prongs and a rear pair of prongs spaced from the front lug and from one another, the prongs of the intermediate and rear pairs extending radially outwards through respective passages in the hollow body in the installed state of the connector and bendable so as to conform to an outer surfaces of the hollow body to prevent displacement of the elongated spring relative to the hollow body. 8. The connector of claim 6, wherein the elongated springs each have a pair of spaced apart wings extending inwards and operative to engage a helical jacket of the armored cable inserted through the hollow body so that the cable is displaceable frontward in response to rotating the body relative to the cable in one direction and displaceable rearward out of engagement with the body upon rotating the body in a direction opposite to the one direction. 9. The connector of claim 8, wherein the wings have respective lengths differing from one another, the wings each having a slanted free end configured to engage a spiral of the helical jacket of the armored cable and biased thereagainst to maintain constant contact with the cable for providing grounding of the cable. 10. The connector of claim 1, wherein the hollow body has a front bushing and a shaft coupled to the bushing and extending rearwards therefrom, the bushing and shaft having respective collar and flange spaced apart and extending radially outwards from the hollow body so as to define a groove therebetween. 11. The connector of claim 10, further comprising a washer having an outer periphery provided with the second biasing component, the washer being coupled to the collar of the bushing having a plurality of spaced-apart notches, the second biasing component extending frontward through the plurality of spaced-apart notches and terminating beyond the collar so as to resiliently press against the outer face of the wall of the wiring box in the installed state of the connector. 12. The connector of claim 11, wherein the second biasing component has a plurality of angularly spaced-apart flexible fingers extending through the respective notches of the collar of the bushing in the installed state of the connector. 13. The connector of claim 11, wherein the washer has an inner periphery provided with a plurality of spaced apart arms extending rearwards over the groove towards and pressing against the flange of the shaft so as to displaceably fix the washer to the collar of the bushing. 14. The connector of claim 1, wherein the hollow body is configured with a collar extending radially outwards from the hollow body and formed integrally with the second biasing component, the second biasing component having a plurality of spaced apart fingers extending frontward beyond the collar and resiliently pressing against the outer face of the wall of the wiring box in the installed state of the connector. 15. The connector of claim 1, further comprising an isolator insertable into the hollow body through a frond end thereof and configured to prevent chaffing of electrical wires of the armored cable. 16. A connector configured to receive an armored cable and mountable to a wall of a wiring box, comprising: an elongated hollow body extending along a longitudinal axis between spaced front and rear ends of the hollow body; a plurality of spaced elongated springs extending through the hollow body and coupled thereto, the elongated springs each having a lug extending through the front end of the hollow body and operative to resiliently press against an inner side of the wall of the wiring box in an installed state of the connector; a support assembly extending radially outwards from the hollow body between the front and rear ends thereof; and a plurality of spaced-apart fingers provided on the support assembly and operative to resiliently press against an outer side of the wall of the wiring box in the installed state of the connector, wherein the lugs and fingers generate respective biasing forces directed in opposite axial directions in the installed state of the connector and minimizing involuntary displacement of the connector relative to the wiring box. 17. The connector of claim 16, wherein the support assembly is configured with a collar integrally provided on the hollow body and a washer mountable to the collar and having the plurality of fingers, the collar having a plurality of spaced peripheral notches traversed by the respective fingers, the fingers terminating beyond the collar so as to press against the outer side of the wall of the wiring box in the installed state of the connector. 18. The connector of claim 17, wherein the lugs of the respective springs each have a plurality of leaves displaceable relative to one another upon pressing against the inner side of the wall, the lugs being biased radially outwards by the armored cable extendable through the hollow body, wherein the armored cable and the lugs are in continuous contact to provide grounding of the cable. 19. The connector of claim 18, wherein the springs each have a pair of wings extending radially inwards and configured to resiliently engage a helical thread of a jacket of the armored cable, the wings being deflected upon frontward linear displacement of the armored, but operative to slide along the helical thread while the connector being rotated to allow rearward displacement of the cable out of engagement with the hollow body.
