A connector system is provided for connecting parts of an apparatus. A first part having one or more bayonet connectors and one or more retention pin receptacles cooperatively mates to a second part having one or more mating bayonet connectors. The second part further provides one or more retention pin bores. The first and second parts assemble to form a bayonet connection such that at least one pin retention bore aligns with at least one retention pin receptacle. At least one retention pin assembly disposed through the at least one pin retention bore selectively engages the retention pin receptacle to secure the connection of the first part to the second part of the apparatus.
