A mounting clip suitable for securing a mesh panel between a stopper element and an eccentric pin joiner of a barricade system, the mounting clip comprising: a tubular clip to secure the mesh panel to a tubular surface, the tubular clip comprising two arms which mirror one another and form a generally cylindrical opening into which the tubular surface is inserted when in use, the arms each including a hole that enables a pin to be inserted there between to enclose the tubular surface therein, the tubular clip also including a first aperture for securing an eccentric pin joiner thereon, and a notch that is located between the two arms configured to enable a removal tool to be inserted therein to facilitate removal of the tubular clip from the tubular surface; a pin inserted through the hole in each of the arms to enclose the tubular surface within the tubular clip; an eccentric pin joiner having a generally oval shaped body, a first projection located on a first side and adapted to pivotally engage the first aperture of the tubular clip, and a second projection located on an opposing second side, the first and second projections (106A, 106B) extending perpendicularly with respect to the body of the eccentric pin joiner in opposing directions such that the first projection is generally parallel and offset with respect to the second projection, the first projection having a circumferentially extending flange adapted to engage with the first aperture of the tubular clip and the second projection having a circumferentially extending flange adapted to engage with a centrally formed hole in a stopper element, the flanges comprising one or more frustoconical portions or a flared, barbed head located at or near the end of the respective projections (106A, 106B); and a stopper element having a generally circular body and a centrally formed hole secured to the second projection of the eccentric pin joiner. a tubular clip to secure the mesh panel to a tubular surface, the tubular clip comprising two arms which mirror one another and form a generally cylindrical opening into which the tubular surface is inserted when in use, the arms each including a hole that enables a pin to be inserted there between to enclose the tubular surface therein, the tubular clip also including a first aperture for securing an eccentric pin joiner thereon, and a notch that is located between the two arms configured to enable a removal tool to be inserted therein to facilitate removal of the tubular clip from the tubular surface; a pin inserted through the hole in each of the arms to enclose the tubular surface within the tubular clip; an eccentric pin joiner having a generally oval shaped body, a first projection located on a first side and adapted to pivotally engage the first aperture of the tubular clip, and a second projection located on an opposing second side, the first and second projections (106A, 106B) extending perpendicularly with respect to the body of the eccentric pin joiner in opposing directions such that the first projection is generally parallel and offset with respect to the second projection, the first projection having a circumferentially extending flange adapted to engage with the first aperture of the tubular clip and the second projection having a circumferentially extending flange adapted to engage with a centrally formed hole in a stopper element, the flanges comprising one or more frustoconical portions or a flared, barbed head located at or near the end of the respective projections (106A, 106B); and a stopper element having a generally circular body and a centrally formed hole secured to the second projection of the eccentric pin joiner.
