The extension length of the connecting portion 12 can be specifically determined according to the distance to be spaced between the pipe and the member to be assembled.

Protruding 15 of anticreep is kept away from the one end in hook groove 111 notch and is connected with connecting portion 12, and the relative connecting portion 12 of the other end of the protruding 15 of anticreep extends along the direction slope towards hook groove 111 notch, this kind of setting for under the non-atress effect, the relative connecting portion 12 slope of the protruding 15 of anticreep, so that the protruding 15 free end of anticreep outwards bulge connecting portion 12 with the card support the pipe fitting. And the setting of this kind of anticreep arch 15, simple structure, processing is convenient.

Preferably, in order to improve the anti-slip function of the anti-slip projection 15 on the pipe, when the pipe is located in the hook groove 111, the end of the anti-slip projection 15 abuts against the pipe. In other embodiments, the free end of the anti-slip projection 15 may also extend to the upper end of the notch of the hook groove 111 but not abut against the pipe. Further, the height of the protruding connection portion 12 at the free end of the anti-dropping protrusion 15 is less than or equal to half of the width of the notch of the hook groove 111 by one third, so that after the pipe is clamped into the hook groove 111, the free end of the anti-dropping protrusion 15 can abut against the position of the pipe opposite to the groove bottom of the hook groove 111 as far as possible, the effect of preventing the pipe from dropping is further enhanced, and meanwhile, the protruding height of the anti-dropping protrusion 15 can be prevented from excessively blocking the pipe from dropping out of the hook groove 111.

In this embodiment, the retaining protrusion 15 is formed by punching the connecting portion 12, that is, a notch is formed on the connecting portion 12 at a position corresponding to the retaining protrusion 15, and when the retaining protrusion 15 is pressed, the retaining protrusion 15 can be trapped in the notch, so that the retaining protrusion 15 is flush with the connecting portion 12. This kind of mode of setting can simplify linking bridge 1's processing and overall structure, reduces the processing degree of difficulty and processing cost. In other embodiments, the retaining protrusion 15 may also be formed in other structures, for example, the retaining protrusion 15 may be made of an elastic material capable of elastic expansion, or the retaining protrusion 15 and the connecting portion 12 may be connected by a spring or other structures capable of elastic expansion.
