An electrical plug safety device (10) comprising a body (16) having apertures for receiving pins (14) of an electrical plug (12). A securing member 32 is provided within the body (16) to engage with a side of at least one of said pins (14) when the pins (14) are received in the apertures such that engagement between the securing member (32) and the side of the pin (14) restricts removal of the plug (12) from the body (16). When sufficient force is applied to the body (16) in a direction away from the plug (12), the securing member (32) is disengaged from the pin (14) and moves such that the securing member (32) will not re-engage with a pin (14) inserted into the body (16).
