A medical closure device (20) is provided, comprising a tubular member (21) provided with first struts (22) that extend between a first end portion (24) and a central portion (25) and second struts (23) that extend between said central portion and a second end portion (26), each strut being provided with a hinge section (27, 28), such that said closure device is movable between a first elongated introduction configuration and a second positioning configuration in which the first and/or second end portions have been moved towards each other such that the first and/or second struts have moved radially away from a longitudinal central axis of the closure device. The closure device further has a third configuration, in which a locking member (30) is positioned in the tubular member such that the first end portion abuts the radial protrusions of a first end (32) of the locking member and the radial protrusions of a second end (36) of the locking member prevents further compression of the tubular member, Additionally, the closure device has a fourth configuration in which the second end portion has been forced over the radial protrusions of a second end such that the closure device is held in an expanded and locked configuration.
