The invention relates to a flat contact socket (1) with a connection section (3) for electrically connecting to an electrical conductor and to a flat contact receptacle (9), which extends along a flat contact plane (11) in a socket body (7), which is spaced apart from the connection section (3), and into which a flat contact (63) can be inserted through an insertion opening (13) along the insertion direction (17), wherein the flat contact socket (1) has at least one blocking element (15) which is opposite the insertion opening (13) in the insertion direction (17) and which delimits the flat contact receptacle (9) at least in the insertion direction (17). In order to provide a flat contact socket (1) which is compact, can be produced cost efficiently, and allows flat contacts with touch protectors to be received, it is intended according to the invention that the at least one blocking element (15) protrudes transverse to the insertion direction (17) from at least one cantilever (31) which extends in the insertion direction (17).
