A connection device has a main block (10), two pushing blocks (20) and two fasteners (40). The main block (10) has two inclined surfaces (100), a long side (101) and a short side (102), two inner threads (120) are formed in the main block (10) and extending to one of the sides (101,102). The pushing blocks (20) are attached respectively to the inclined surfaces (100), and each pushing block (20) has a body (21), an inclined surface (210) and two resilient tongues (24). The resilient tongues (24) are formed on the body (21) and each have a free end and an engaging protrusion (240) formed on and protruding from the free end. The fasteners (40) are inserted into the main block (10), and each fastener (40) has a thread screwed with one of the inner threads (120) in the main block (10). |
