<p>A removable core cylinder lock with a cylinder lock casing and a removable cylinder lock core (20) inserted into the casing. The lock core has an upper massive part (22) with a row (25) of holes for accomodating locking tumblers (26, 66) and a lower part (23) defining a cylindrical bore (24), in which a cylindrical, rotatable key plug (60) is located. The lower part (23) defining the cylinder bore (24) of the cylinder lock core (20) is partially cut away so as to form an axially elongated chamber (30) accomodating a transversely movable retainer member (40) and leaving a continuous lower wall portion (23a). The retainer member has an axial length, which corresponds to at least half of the axial length of the row (25) of holes in the upper massive part, and a limited circumferential extension, which is substantially supplementary to the continuous lower wall portion so as to define said cylindrical bore (24).</p> |
