DISMANTLE-PREVENTION CONNECTOR

An anti-disassembly connector, including: a connecting portion (10), where a threaded connecting section (11) is disposed on the connecting portion (10); and bosses (20), where the bosses (20) protrude from an end or a peripheral wall of the connecting portion (10), each of the bosses (20) extends along a circumferential edge or the peripheral wall of the connecting portion (10), each of the bosses (20) has a force-bearing surface (21) and a force-releasing surface (22) that are disposed opposite to each other, at least two bosses (20) are arranged, the two bosses (20) are disposed at intervals along the circumferential edge or the peripheral wall of the connecting portion (10), and a gap between two adjacent bosses (20) forms a clamping interval. A force-bearing sideline (211) is formed on a side of the force-bearing surface (21) away from an inner wall of the connecting portion (10), a length of the force-bearing sideline (211) is L, and 5 mm < L < 20 mm. The technical problem that a pipe joint is easily disassembled due to a misoperation in the art known to inventors can be solved by means of the anti-disassembly connector.
