A telescopic handle has a first tube with two slots and a second tube with two holes. A locking element has a first section attached in the first tube and a larger second section sited in the second tube. The second section of the locking element has two holes. A passage with a first section and a larger second section is formed through the locking element. A plunger has a first section insertable through the first section of the passage, a second section with a cross-sectional profile marginally smaller than that of the second section of the passage and a third section with a cross-sectional profile smaller than that of the second section of the passage. A spring is compressed between the second section of the plunger and a nut attached to the third section of the plunger. A pulling element links a bolt, insertable through the slots, to the first section of the plunger. Two balls are sited in the holes formed through the locking element. The plunger is spring-biased so that the second section of the plunger aligns with the holes formed through the locking element for pushing the balls partially into the holes formed in the second tube, thereby retaining the first tube relative to the second tube. The plunger is moveable, by pulling the bolt, so that the third section of the plunger aligns with the holes formed through the locking element for allowing the balls to be pushed partially into the holes formed through the locking element, thereby allowing the first tube to slide relative to second tube.

A telescopic handle for carts, comprising: a first tube comprising two opposing slots longitudinally formed therethrough near one end thereof; a second tube comprising two holes formed therethrough near one end thereof; a locking element comprising a first section attached in said first tube and a relatively large second section attached in said second tube, said second section of said locking element comprising two holes transversely formed therethrough, said holes formed through said locking element comprising a diameter greater than that of said holes formed through said second tube; a passage being axially formed through said locking element and comprising a first section and a relatively large second section; a plunger comprising a first section being insertable through said first section of said passage, a second section comprising a cross-sectional profile being marginally smaller than that of said second section of said passage and a third section comprising a cross-sectional profile being smaller than that of said second section of said passage; a nut attached to said third section of said plunger; a spring mounted on said third section of said plunger so that said spring is compressed between said locking element and said nut; a bolt being insertable through said slots; a pulling element linking said bolt to said first section of said plunger; two balls being respectively sited in said holes formed through said locking element and comprising a diameter greater than the wall thickness of said second section of said locking element; said plunger being biasable, by means of said spring, to a first position relative to said locking element so that said second section of said plunger is aligned with said holes formed through said locking element for pushing said balls partially into said holes formed in said second tube, thereby retaining said first tube relative to said second tube; said plunger being moveable, by pulling said bolt upwards, to a second position with respect to said locking element so that said third section of said plunger is aligned with said holes formed through said locking element for allowing said balls to be pushed partially into said holes formed through said locking element, thereby allowing said first tube to be further inserted into said second tube.
