20 is illustrated as an essentially permanent or non removable connection it may be desired to provide a removable or releasable connection between the connector 12 and the housing 14 and this may be accomplished in a conventional fashion for example by rounding the rearwardly facing edge 92 of the tab 82 the rearward end 94 of the connector 12 forms an insulation displacing connector region generally indicated as 96 a hinged strain relief cover 98 is connected to the housing 16 by a pair of hinges 100 conveniently integrally formed with the remainder of the connector 12 by plastic molding techniques the cover 98 includes a plurality of transversely arranged downwardly extending teeth 102 separated by troughs 104 in addition a pair of spaced apart apertures 106 are formed in the cover 98 to mate with catches 108 on the end 94 the catches 108 are cam shaped to facilitate a connection between the catches 108 and the apertures 106 while resisting opening of the cover 98 with respect to the housing 16 in this way the cover 98 may be pivoted from an open position as shown in fig4 to a closed position shown in fig3 with its teeth 102 against the upper surface 80 when the cover 98 is in its open position as shown in fig4 a plurality of wire receiving receptacles 110 defined by upstanding tongues 116 with tapered upper ends 118 are exposed in the illustrated embodiment the receptacles 110 are arranged in an upper row 112 and a lower row 114 as shown in fig3 and 4.
