oppositely spaced on body portion 64 to receive and retain retaining cams 60 and 62 when bifurcated end 32 is located within cavity 66 in a preferred embodiment the retaining cams 60 and 62 are located diametrically opposed from one another the locking window 70 and 72 are similarly located to correspond to the location of retaining cams 60 and 62 as best shown in fig3 the locking windows may be of a shoe shape or u201c l u201d configuration each having a longitudinally extending entry slot 74 that terminates in a laterally or circumferentially extending slot 76 to retain retaining cams 60 and 62 as illustrated in fig5 in its preferred embodiment strain relief cap 26 is a cylindrical cup shaped member having axially extending entry slots opening into the open end of the cap wire slots 78 and 80 have been positioned diametrically opposed from one another to receive wire 28 it should be appreciated that only one wire slot 78 is needed if it is chosen to terminate center portion 40 within cavity 66 of strain relief cap 26 wire slots 78 and 80 may be configured similar to locking windows 70 and 72 further although bifurcated end 32 may extend upwardly from a side surface of contact 22 it is preferred to bend it in a know matter relative to the side surface toward the axis of cylindrical portion 30 and then upwardly along the axis to center the bifurcated end 32 relative to cylindrical portion 30 as illustrated in fig3 in this manner a cylindrical cap 26 can.
