Self-retaining anchoring assembly and seal therefor

A self-retaining anchoring assembly for mounting a coaxial cable within a throughbore defined in a support member, the coaxial cable including concentrically arranged inner and outer cable members, comprising:

• inner and outer concentrically arranged sleeve members providing cooperating abutment means at one end, and an annular collar mounted concentrically about the outer sleeve member adjacent said one end in fixed relation thereto, the outer sleeve member providing a plurality of integral, circumferentially spaced resilient external prongs extending towards said one end and spaced from the annular collar by a distance equal to the thickness of the support member whereby to retain the assembly in the throughbore with the annular collar and the ends of the prongs engaging respectively opposite faces of the support member, and
• a first annular seal of resilient flexible material arranged concentrically with the sleeve members and extending from the other end thereof, said first annular seal providing a first annular end portion clamped between said inner and outer sleeve members, a second annular end portion providing internal sealing means positioned to engage the inner cable member in wiping relation thereto, and an intermediate portion extending from the first annular portion to the second annular portion and formed with integral annular corrugations.
