The cylindrical wall extends between a first end configured for attachment within a cavity of the textile sleeve and a second end having a radially outwardly extending annular rim configured for attachment to the electrical connector. The cylindrical wall has at least one radially outwardly extending annular bead adjacent the first end with the annular bead providing a radially inwardly facing annular pocket. At least one seal member is disposed in the cavity for sealed abutment with the inner surface and the elongate electrical member. ## Claims ### Claim 1 A ferrule configured to couple a textile sleeve to an electrical connector, comprising: a cylindrical wall having an inner surface providing a cavity sized for receipt of an elongate electrical member therethrough, said cylindrical wall extending between a first end configured for attachment within a cavity of the textile sleeve and a second end having a radially outwardly extending annular rim configured for attachment to the electrical connector, said rim provides a generally C-shaped annular pocket adjacent said second end and further comprising an elastomeric seal disposed in said generally C-shaped annular pocket, said cylindrical wall having at least one radially outwardly extending annular bead adjacent said first end with said annular bead providing a radially inwardly facing annular pocket; and at least one seal member disposed in said cavity for sealed abutment with said inner surface and the elongate electrical member. ### Claim 2 (depends on 1) The ferrule of claim 1 wherein said at least one seal member is disposed in said pocket. ### Claim 3 (depends on 1) The ferrule of claim 1 wherein said at least one seal member extends between said pocket and said second end. ### Claim 4 (depends on 3) The ferrule of claim 3 wherein said at least one seal member is fixed to said inner surface of said cylindrical wall. ### Claim 5 (depends on 4) The ferrule of claim 4 wherein said at least one seal member is bonded to said inner surface of said cylindrical wall. ### Claim 6 (depends on 1) The ferrule of claim 1 wherein said cylindrical wall has at least two radially outwardly extending annular beads spaced axially from one another by an annular recess with each of said beads providing a radially inwardly facing annular pocket. ### Claim 7 (depends on 6) The ferrule of claim 6 wherein said at least one seal member includes a plurality of seal members with a separate one of said seal members disposed in each of said pockets. ### Claim 8 (depends on 1) The ferrule of claim 1 wherein said at least one radially outwardly extending annular bead is a half bead. ### Claim 9 (depends on 1) The ferrule of claim 1 wherein said at least one radially outwardly extending annular bead is a full bead forming said radially inwardly facing annular pocket having a concave contour. ### Claim 10 A ferrule in combination with an electrically conductive textile sleeve, an elongate electrical member received in said textile sleeve, and an electrically conductive electrical connector, said ferrule comprising: a cylindrical wall having an inner surface providing a cavity sized for receipt of said elongate electrical member therethrough, said cylindrical wall extending between a first end configured for attachment within a cavity of said textile sleeve and a second end having a radially outwardly extending annular rim configured for attachment to said electrical connector, said rim provides a generally C-shaped annular pocket adjacent said second end and further comprising an elastomeric seal disposed in said generally C-shaped annular pocket, said cylindrical wall having at least one radially outwardly extending annular bead adjacent said first end with said annular bead providing a radially inwardly facing annular pocket; and at least one seal member disposed in said cavity for sealed abutment with said inner surface and said elongate electrical member. ### Claim 11 (depends on 10) The combination of claim 10 wherein said at least one seal member is disposed in said pocket. ### Claim 12 (depends on 10) The combination of claim 10 wherein said at least one seal member extends between said pocket and said second end. ### Claim 13 (depends on 12) The combination of claim 12 wherein said at least one seal member is fixed to said inner surface of said cylindrical wall. ### Claim 14 (depends on 13) The combination of claim 13 wherein said at least one seal member is bonded to said inner surface of said cylindrical wall. ### Claim 15 (depends on 10) The combination of claim 10 wherein said cylindrical wall has at least two radially outwardly extending annular beads spaced axially from one another by an annular recess with each of said beads providing a radially inwardly facing annular pocket. ### Claim 16 (depends on 15) The combination of claim 15 wherein said at least one seal member includes a plurality of seal members with a separate one of said seal members disposed in each of said pockets. ### Claim 17 (depends on 10) The combination of claim 10 wherein said at least one radially outwardly extending annular bead is a half bead. ### Claim 18 (depends on 10) The combination of claim 10 wherein said at least one radially outwardly extending annular bead is a full bead forming said radially inwardly facing annular pocket having a concave contour.
