The term 'Connecting Peg' can be defined as a DOWEL, which is a cylindrical rod made of wood, metal, or plastic. It is used to join two pieces of material together, such as wood or metal, and is often used in carpentry and construction. The DOWEL is inserted into a hole drilled in the two pieces of material, and then secured with glue or nails. Connecting pegs are also used in furniture assembly, as well as in other applications where two pieces of material need to be joined together.
