More specifically, the present invention can be used as part of a barricading system that is installed to a wide variety of platform, walkways and stairway designs. The present invention can also be used as a machine guarding system. BACKGROUND TO THE INVENTION [0002] The following discussion of the background to the invention is intended to facilitate an understanding of the invention. However, it should be appreciated that the discussion is not an acknowledgement or admission that any of the material referred to was published, known or part of the common general knowledge as at the priority date of the application. [0003] Since 2001, there has been a growing demand in the Mineral Resources and Construction sectors across Australia. Currently, during on site shut downs there is a high cost of setting up and disassembling temporary barricading in order to combat the hazard of potentially fatal dropped objects. Innovative products are required to combat the increasing safety issue of dropped objects from elevated platforms, walkways and stairways. [0004] It would therefore be desirable to provide a stop drop barricading system designed to provide a safety system that is universal, cost effective and easy to install wherever the application is required to prevent dropped objects. SUMMARY OF THE INVENTION [0005] The present invention provides in a first aspect a mounting clip for a barricade and/or guarding system, the mounting clip comprising: A. at least one clip having a first engagement formation adapted to secure the clip to a fixed structure, the first engagement formation including at least one of: a channel including angled teeth, the angled teeth being directed toward a base region of the channel, and presented at an angle such that upon insertion of an object therein, the angled teeth inhibit removal of said object from the channel; or a tubular clip having two spaced apart arms between which a portion of the fixed structure is received, the clip further having a connection aperture; 3 B. a joiner element having a first projection located on a first side, and a second projection located on an opposing second, the first projection being adapted to engage the connection aperture of the clip to secure the joiner element to the clip; and a stopper element having a stopper aperture, the stopper aperture being engageable with the second projection to secure the stopper element to the joiner element, wherein the first projection is pivotally engaged with the connection aperture, and the second projection is eccentric relative to the first projection. [0001] In some embodiments, the first projection and the second projection are generally parallel and offset relative to each other. [0002] In a second aspect, the present invention relates to a barricade and/or guarding system comprising: at least one mounting clip according to the first aspect of the present invention; and at least one mesh panel; wherein in use, a portion of the mesh panel is located between the stopper element and the joiner element. [0003] In some embodiments, the barricade and/or guarding system further comprises a joiner assembly to secure adjacent sections of said mesh panel to one another.
