A telescoping member comprising an inner tubular member nested in an outer tubular member and movable between a retracted position and an extended position in telescoping relation, in which the inner tubular member is releasably lockable to the outer tubular member in the extended position by a resilient ledge cooperating with a fixed ledge, the resilient ledge being disposed within a longitudinal channel defined between an inner surface of the outer tubular member and an outer surface of the inner tubular member. An enlarged lower portion of the inner tubular member engages against an inwardly directed lip at the top of the outer tubular member such that the inner tubular member is prevented from being pulled out of the outer tubular member. Upon the application of axial force to the inner tubular member the resilient ledge is depressed, allowing the resilient ledge to travel past the fixed ledge so that the inner tubular member can move to the retracted position. A plurality of tubular members can be used to form a handle for a luggage item.

[I claim:] [1.]an outer tubular member having a lower portion and an upper portion having an open top end,an inner tubular member having a lower portion disposed through the open end of the outer tubular member and an upper portion, the inner tubular member being slidably disposed within the outer tubular member and movable between a retracted position and an extended position in telescoping relation,at least one longitudinal channel defined between an inner surface of the outer tubular member and an outer surface of the inner tubular member,the inner tubular member being releasably lockable to the outer tubular member in the extended position by a locking mechanism comprising the upper portion of the outer tubular member providing a first ledge, and the lower portion of the inner tubular member providing a second ledge, at least one of the first ledge and the second ledge being a resilient ledge having a rest condition and a depressed condition wherein in the rest position the resilient ledge is disposed within the longitudinal channel,whereby in the extended position the first ledge projects into a space defined by the outer tubular member and abuts against the second ledge to releasably lock the inner tubular member in the extended position, and upon the application of axial force to the inner tubular member the resilient ledge is forced to the depressed condition allowing the first ledge to travel past the second ledge so that the inner tubular member can move to the retracted position.
