Abstract
A removable core cylinder lock includes a cylinder lock casing and a removable cylinder lock core inserted into the casing. The lock core has an upper massive part with a row of holes for accommodating locking tumblers, and a lower part defining a cylindrical bore in which a cylindrical, rotatable key plug is located. The lower part defining the cylinder bore of the cylinder lock core is partially cut away so as to form an axially elongated chamber accommodating a transversely movable retainer member and leaving a continuous lower wall portion. The retainer member has an axial length, which corresponds to at least half of the axial length of the row 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 the cylindrical bore.
