A modular fence comprises transverse bars (10), vertical bars (9) and clamping elements (3). The clamping elements (3) are non-metal elastic pieces. The vertical bars (9) are in clamped connection with the clamping elements (3) through vertical bar inserting holes (3-2) formed on the middle parts thereof. Outer rings of the clamping elements (3) are in inserted connection with the inserting holes (10A) of the transverse bars, outward flanges (3-1) are arranged at the upper end of the outer rings of the clamping elements (3). Slopes (3-5) inclining towards the inner side are arranged on the outer rings below the flanges (3-1). The lower sides of the slopes (3-5) are straight sides (3-4), the outer diameters of the straight sides (3-4) being smaller than that of the flanges (3-1) at the upper ends. Clamping groove (3-6), which are matched with the single side thickness of profiles of the transverse bars (10), are formed between the upper end faces of the slopes (3-5) and the lower end faces of the flanges (3-1). The inner ring faces of the clamping elements (3) corresponding to the slopes (3-5) on the outer ring are provided with protrusions (3-7) protruding inwards. The protrusions (3-7) extend out in a circular-arc shape from the top down, and stretch into clamping holes (9-1) in the vertical bars (9). The lower end faces (3-8) of the protrusions (3-7) abut against the openings of the clamping holes (9-1). The fence can be assembled on site, and the cost is reduced.
