Abstract
An arrangement for connecting tubular articles, particularly piles and pile sleeves, in which a first tube (4) fits into a second tube (2), the first tube having a first circumferential recess (10) and a second circumferential recess (12), and the second tube has a first set of latches (8) and a second set of latches (8′) which are resiliently biased to engage in the first and second recesses respectively. When the latches and the recesses are mutually engaged, axial movement is prevented by abutments in the recesses and the latches by one set of latches in one direction and the other set of latches in the opposite axial direction. Latching engagement is only possible when the first set of latches is opposite the first recess and the second set opposite the second recess. This ensures positive connection and the use of preferred elements (30) which extend from one set of latches through the outer casing of the second tube. A mechanism can be provided to readily unlatch the tubes. In another arrangement, a similar unlatching arrangement is used, comprising a set of latches (118) which locate in a recess (117′) bounded by a circumferential abutment surface (117). The latc…
