A fastening device for fastening a rope comprises a main body which includes a base, two spaced-apart legs extending longitudinally from the base and each having one end extending away from the base, and a first cross bar, a second cross bar and a third cross bar spaced from one another and disposed transversely between the two legs in that order from the base to the ends of the legs. The third cross bar is movable to a first position proximate the second cross bar or to second position distal from the second cross bar. First, second and third spaces are defined by the third cross bar with the second cross bar, the second cross bar with the first cross bar, and the first cross bar with the base, respectively, for passage of the rope. A ring member is pivotally mounted in the ends of the legs.

What is claimed is: 1. A fastening device for fastening a rope, comprising: a main body including a base, two spaced-apart legs extending longitudinally from said base and each having one end extending away from said base, and a first cross bar, a second cross bar and a third cross bar disposed transversely between said two legs and arranged in spaced-apart manner in a direction from said base to said ends of said legs wherein said first cross bar is adjacent said base, said second cross bar is adjacent said first cross bar and said third cross bar is adjacent said second cross bar, said third cross bar being movable to a first position proximate said second cross bar or to a second position distal from said second cross bar, said third cross bar defining a first space with said second cross bar, said second cross bar defining a second space with said first cross bar and said first cross bar defining a third space with said base; and a ring member pivotally mounted in said ends of said two legs, wherein said first, second and third spaces are adapted to permit passage of the rope, and said third cross bar is movable toward said second cross bar to said first position to clamp a portion of the rope against said second cross bar when the rope is pulled. 2. The fastening device of claim 1, wherein said two legs are provided with two slots, respectively, which are elongated in the longitudinal direction of said legs, and said third cross bar has two opposite ends inserted movably into said two slots, respectively. 3. The fastening device of claim 1, wherein said third cross bar is provided with a roughened outer surface. 4. The fastening device of claim 1, wherein said first cross bar is provided with a roughened outer surface. 5. The fastening device of claim 1, wherein said second cross bar is provided with a roughened outer surface. 6. The fastening device of claim 1, wherein said first and second cross bars are both provided with a roughened outer surface. 7. The fastening device of claim 1, wherein said base is composed of a flat section proximate said two legs and a bent lever section distal from said two legs and connected to said flat section. 8. The fastening device of claim 1, wherein said third cross bar has an outer surface provided with a concave portion facing said second cross bar. 9. The fastening device of claim 8, wherein said outer surface of said third cross bar is provided with a convex portion opposite said concave portion. 10. The fastening device of claim 2, wherein said two slots of said two legs taper in size toward said second cross bar thus forming two tapered ends proximate to said second cross bar, respectively, said third cross bar being in said first position when said two opposite ends of said third cross bar are moved to said tapered ends. 11. The fastening device of claim 10, wherein each of said opposite ends of said third cross bar has an insert piece inserted into one of said slots, said insert piece being elongated in said longitudinal direction of said legs and having a flat face in sliding contact with an edge confining said one of said slots.
