A coupler which is adapted to be connected to a complementary device for the transfer of a fluid between the coupler to the complementary device comprises a body through which the fluid is allowed to flow, at least one seal for providing a fluid-tight seal between the coupler and the complementary device, and a protecting device for the seal. The protecting device is movable between a first position before connection in which the protecting device projects beyond the seal in the direction of connection, and a second position after connection in which the protecting device no longer projects beyond the seal. The coupler also includes a damper for urging the protecting device towards its first position.
