Abstract: A coaxial cable end connector for connecting a cable to a terminal has inner and outer spaced concentric sleeves, the outer sleeve provided with sealing rings which are formed out of the thickness of the outer sleeve along a crimping zone of the sleeve to minimize the crimping force required to crimp the outer sleeve by inward radial deformation into sealing engagement with the cable. Preferably, the wall thickness of at least a portion of the outer sleeve is reduced in order to further reduce the crimping force required to deform the sleeve into sealing engagement with the cable. In certain applications, an external annular seal is interposed between confronting surface portions of one of the inner and outer sleeves and a coupling member which makes up onto the terminal in sealing against moisture infiltration.
