摘要： A door closer includes a plate-shaped mounting bracket and a closer body. The bracket is secured to a door. The closer body is secured detachably to the bracket by a particular tongue and groove engagement and a fastener. The closer body has an opening which is sized so that the bracket can be completely concealed by the closer body. After the fastener is removed, the closer body can slide within the bracket. The closer body has two opposed side walls each having an inner surface which has longitudinally spaced-apart grooves. The bracket body has two opposed sides on each of which spaced-apart tongues are provided for engaging with the grooves. The closer body can be sleeved on the bracket and then moved laterally relative to the bracket so as to achieve the tongue and groove engagement.
