A critical issue for complex software architecture design is the modeling and analysis of connectors. This paper argues for an approach to composite reuse of connectors based on reflection. To support this notion a set of mata-operations of connectors composition steming from the operations between processes in CSP have been identified, and the CSP semantics of composite connector are also provided. As it will be shown that it provides mechanisms for designing connectors in an incremental way, and can be analysed and checked automatically owing to the formal basis.
