Abstract

An inspection cover, comprising a perimetric frame (11) to be embedded in the ground and to which a lid (12) is pivoted which is suitable to be arranged, in the closed configuration, within a complementarily shaped annular wall (13) of the frame (11), an internal annular portion (14) of the lid (12) being designed to rest on a corresponding shoulder (15) which protrudes within the frame (11) by way of the interposition of an annular sealing element (17); the lid (12) can be closed onto the frame (11) with reversible locking means. The reversible locking means are constituted by at least one elastically flexible bar (18, 19), which is formed on the internal annular portion (14) of the lid (12) and monolithically therewith; the at least one bar (18, 19) has a raised portion (20, 21) which is suitable to engage by snap action within a corresponding recess (22, 23) formed on the internal surface (16) of the annular wall (13) of the frame (11).
