A pipe clip (2) comprising a body portion (4), a closure portion (6), a hinge (8) enabling the closure portion (6) to open and close with respect to the body portion (4), a pipe-receiving aperture (10) for receiving a pipe, and a pair of wing members (14) defining a part of the pipe-receiving aperture (10), and the pipe clip (2) being such that each wing member (14) is flexible about one end (16) which is connected to the body portion (4), the size of the pipe- receiving aperture (10) is able to be increased by flexing of the wing members (14), the flexing of the wing members (14) is caused by pressure on the wing members (14) from a pipe (18) of a diameter requiring the pipe-receiving aperture (10) to be increased in size from a size determined by the wing members (14) when they are not flexed, and the closure portion (6) moves between its open and closed positions independently of the flexing of the wing members (14).
