or plastic conical tip 44 is sealed bonded by contact pin 38 and outer contact layer 42 thereby blocking the passage of water or other fluid through the male probe and into the interior of the cable or vice versa contact pin 38 projects beyond the tip 44 which allows the male contact probe to be pushed easily through the seal outer conductor 32 of the coaxial cable is pushed over the outside of outer contact layer 42 to an enlarged annular rib 46 formed on the contact layer and is secured by soldering crimping or other suitable means the connection is encased in an insulated boot 48 formed by potting the assembly in a suitable mold with neoprene or similar material the boot encloses rib 46 to lock the connection in place and extends outwardly along the cable 26 to provide support boot 48 seats in a retaining collar 50 which fits through opening 18 and has a shoulder 52 which bears against the inside of end wall 16 the protruding end of retaining collar 50 is slit longitudinally to form prongs 54 which seat in an annular channel 56 in boot 48 to secure the collar on the boot a snap ring 58 is snapped into an annular groove 60 in the outside of prongs 54 and bears on the outer end of body 14 to hold the assembly together while allowing the body to rotate on the collar 50 the resiliency of the boot material and the prongs allow the members to be forced into place to obtain.
