Abstract

In order to make it easier to mount for instance playground equipment comprising a tube construction which is anchored to a base the subject invention offers a simplification by incorporating a means to facilitate the longitudinal adjustment of the grooves in relation to the base. This means comprises a tube piece (2) extending in the tube (1), which tube piece is anchored to the base and which is configured with longitudinal folds for the formation of outwardly open channels (4). In these channels (4) a wedge element (3) is inserted which by means of bolts (6) through the tube (1) can tighten the wedge and due to the cross sectional shape of the grooves cause the tube piece (2) to expand so that it squeezes against the inside of the tube (1). In this manner the tube (1) can be adjusted in the longitudinal direction in connection with both the mounting and the subsequent adjustment.
