Abstract

A self-locking manhole cover (4) has stiffening ribs (8, 10, 17, 18) secured to its underside and a locking means (6) on its underside, the locking means (6) being intended to engage beneath the flange (2) of a manhole frame (1) when the cover has been placed in the manhole frame. By action against an elastic force which keeps the locking means (6) beneath the flange (2), the locking means (6) may be released from the locking position by operating a tool (14) which is inserted down through a hole (15) in the manhole cover (4). The locking means (6) consists of a protruding boss which is secured to a resilient arm (5) which is secured to the underside of the cover (4) and extends parallel to its plane and essentially parallel to part of the periphery of the cover (4) and near thereto. The cover (4) is on its underside further provided with at least one further locking means (7) intended to engage beneath the flange (2) of the manhole frame (1) when the cover has been positioned in the manhole frame.
