<p>The device (42) has a rail (44) comprising longitudinal grooves (56, 58) communicating with outside through longitudinal slots (60, 62) arranged in an upper platform (46) of the rail. The grooves have a maximum transverse extent (L58) strictly greater than a transverse extent (L62) of the slot. The groove is associated with a sliding element (90) of the device. The sliding element has a guiding and retaining unit (110) i.e. lateral retaining wing, configured to be engaged in the corresponding longitudinal groove. The wing has a transverse extent (L0) greater than that of the slot. An independent claim is also included for a shelter of a swimming pool.</p> |
