ABSTRACT:
A coupling for axially locking each reel of a cassette relative to the drive wheel of a magnetic recorder in which the drive wheel has an axial abutment against which the reel may bear. The reel is provided with a central recess having at least one rest projecting radially inward. The coupling includes a resilient locking device carried by the drive wheel and a controller slidably mounted within the drive wheel for actuating the resilient locking device between a retracted, rest position in which the reel can freely slide onto the drive wheel, and a working position in which the resilient locking device is pressed against the rest so that the reel can be axially locked against the axial abutment.
