1. A one-piece, self-locking clamp of resilient, flexible plastic, said clamp being adapted to extend circumferentially about a cycle frame member and being further adapted to hold a pair of cable-like members which longitudinally extend along a bicycle frame member in circumferentially spaced relationship without exerting any substantial radial compressive force upon either one of such cable-like members, said clamp comprising:

  • a centrally disposed, elongated mid-section having a front face and a back face and whose facial width is generally substantially greater than the thickness thereof, said mid-section being interrupted at a generally central location by having integrally, permanently formed therein a cross-sectionally U-shaped projection extending transversely across said mid-section outwardly from said front face and inwardly from said back face whose inside width and inside height are adapted to accommodate therewithin a single, prechosen one of said cable-like members, a first thickened portion integrally formed at one end of said midsection having a socket defined therein, a second thickened portion integrally formed at the opposite end of said mid-section having defined permanently therein a cross-sectionally generally U-shaped channel which extends transversely across said midsection outwardly from said front face and inwardly from said back face and whose inside width and inside height are adapted to accommodate therewithin a single prechosen one of said cable-like members, said channel being in longitudinally spaced, parallel relationship to said U-shaped projection, an integrally formed prong projecting from said second thickened portion and adapted to make mating engagement with said socket, said prong having serrated outer side wall portions, which serrated portions are adapted to make yielding, biased engagement with inside wall portions of said socket, thereby adapting said prong to interlock with said socket when so engaged therewith, wherein the axis of said socket is generally normally inclined relative to said midsection and said socket generally upstands relative to said back face in the region of said first thickened portion when said clamp is assembled, wherein the axis of said prong is generally normally inclined relative to said mid-section and said prong generally upstands relative to said back face in the region of said second thickened portion when said clamp is assembled, and wherein behind said socket and behind said prong, and integrally formed one in each of said first and second thickened portions, respectively, shoulders are provided each of which is adapted as a base against which pressure may be manually applied to engage said socket with said prong.
