Disclosed is a plastic cord clamp which comprises a pair of opposed arcuate holding members having the lower ends thereof connected with each other through an intervening thin-walled hinge portion to form a roundly bent main clamp body, said hinges portion being flexible to the extent of allowing said opposed holding members to diverge or converge freely about said hinge portion as the fulcrum, mutually engageable pawls formed one each at the upper ends of said pair of holding members and a pair of leg members formed one each at the lower ends of said pair of holding members and adapted to protrude outwardly therefrom tangentially to the clamp body in opposite directions, whereby said two leg members converge when said upper ends of holding members are opened to admit a cord between the two holding members and the leg members diverge and come into fast engagement with the edges of matching perforations bored in a holder plate when said engaging pawls are closed in on the admitted cord and brought into mutual engagement, with the result that the main clamp body is immobilized relative to the cord as well as the holder plate.
A one-piece plastic cord clamp, which comprises a pair of opposed, substantially rigid arcuate holding members, a hinge portion connecting the lower ends of said pair of holding members, said pair of holding members and said hinge portion being so disposed as to form a main clamp body, a pair of mutually engageable pawls formed one each at the upper ends of said pair of holding members, and a pair of leg members formed one each at the lower ends of said holding members and adapted to initially protrude outwardly therefrom in an angularly diverging relation so that said leg members converge about said hinge portion as a fulcrum when said engaging pawls are opened and the leg members flex about said fulcrum into a substantially co-planar, oppositely extending relationship when the engaging pawls are closed into fast mutual engagement, said pawls including a female portion at the upper end of one holding member and a male portion at the upper end of the other holding member, said female portion including laterally spaced hook means projecting into the mouth of said female portion and said male portion including oppositely facing laterally spaced shoulder means for engaging said hook means whereby said holding portions are positively locked by said male and female portions against both lateral and circumferential openings.
A one-piece plastic cord clamp in combination with an apertured plate-like support member wherein said member includes a pair of apertures spaced by a bridging portion, said clamp including a pair of opposed, substantially rigid arcuate holding members, a hinge portion connecting the lower ends of said pair of holding members, said hinge portion being generally rectangular in configuration and hingedly connected in spaced relation along opposite ends thereof to said holding members, said pair of holding members and said hinge portion being so disposed as to form a main clamp body, a pair of mutually engageable pawls formed one each at the upper ends of said pair of holding members, and a pair of leg members formed one each at the lower ends of said holding members and adapted to initially protrude outwardly therefrom in an angularly diverging relation so that said leg members converge intermediately of said hinge portion as a fulcrum when said engaging pawls are opened said legs initially projecting angularly when telescoped through said spaced apertures and then said leg members flex about said fulcrum into a substantially co-planar, oppositely extending relationship when the engaging pawls are closed into fast mutual engagement, whereby said legs engage the opposite side of said support member adjacent the remote edges of said two apertures when the clamp is closed, said legs being substantially parallel to said support in closed position and said hinge portion engaging the opposite surface of said support in the vicinity of said bridging position.
