A fluid-connection device capable of and intended for connecting a flexible pipe to a flexible or rigid pipe or enclosure in a biopharmaceutical assembly such as to provide fluid communication between two fluid spaces, including a first connector in fluid communication with the first fluid space, a second connector in fluid communication with the second fluid space, the first connector and the second connector optionally being coupled together in a coupling position, the first connector including a tubular nozzle which can be inserted in one end of the pipe, a pipe clamp being arranged around the end of the tube in order to clamp the pipe onto the tubular nozzle of the first connector, the second connector including protection elements which, in the coupling position, are positioned radially at least partially opposite the pipe clamp, whereby the pipe clamp cannot come into direct contact with external elements.
