The invention pertains to a sieve bed for a sifting machine, consisting of rectangular sieve elements ( 10 ), which are attached to a support frame ( 1 ) with their edges abutting each other, the support frame being provided with mushroom-shaped mounting pins ( 3 ), each of which is provided with a head which engages in an interlocking manner in corresponding recesses ( 11 a and 11 b) of the sieve elements ( 10 ). To facilitate the assembly and disassembly of the sieve elements in a sieve bed of this type and to protect the connection from premature wear the invention proposes that the receptacle ( 11 ) for the head ( 4 ) of the mounting pin ( 3 ) be closed off at the top; that the receptacle ( 11 ) for the head ( 4 ) of the mounting pin ( 3 ) be provided at the bottom with an entrance opening for the head ( 4 ) of the mounting pin ( 3 ); and that the wall of the receptacle ( 11 ) be provided with an inward-projecting bead ( 12 ), which can be snapped under the head ( 4 ) of the mounting pin ( 3 ).
