A telescopic rail comprising at least two substantially C-shaped sections of which a first section (1) is slidably mounted in a second section (2) with interposition of a first ball cage (3), whereby a stop block (5) is positioned in said second section, in front of the first ball cage seen in the direction of extension of the rail, the stop block having first resilient means (9) near the side facing the first ball cage which can be brought into contact with a first inward facing projection (18) on the first section upon extension of the rail, and second resilient means (8) on the opposite side of the stop block which can be brought into contact with a second inward facing projection (17) on the first section upon retraction of the rail, the first (18) and second (17) projections being located on opposite sides of the first ball cage when the rail is fully retracted, the first projection being movable past the first ball cage. |
