The device is characterized in that it comprises at least one hollow main body extending longitudinally between two ends, which body is provided with a first opening and is intended to be inserted into the hole (10) and to receive a removable male connector that is to be inserted into the hollow main body through the first opening in order to connect the accessory and the hollow main body. The main body (51) defines a continuous empty inner space that opens at each end in order to form the first opening (511) and a second opening (516). The device is further characterized in that it also comprises a first removable cap for closing the first opening when the male connector is not inserted into the hollow main body. The invention relates to assembly devices and systems for an exercise structure.
