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.
A rail guide comprising several rails with interposed balls, said rails being telescopically slidable together, forming an outer section, an interposed section, and an inner section, and being substantially U-shaped in cross-section, said balls running in concave sections opposing each other in pairs, characterized in that the outer section carries an elastically deformable element extending within the rail system, said element having at least one protuberance directed transversely to the longitudinal axis of this system, while at the inner section at least one notch directed transversely to the longitudinal axis of the rail system is provided, such that it engages behind the protuberance of the elastically deformable element when the rail guide is in the slid-in position, in which position a force can be exerted on the above element by means provided therefor, said force allowing this element to protrude further in the transverse direction.
