PURPOSE:To enable a piping connection state to be checked easily through the deformation of a check member by shifting a slide member, being built-in a joint body, in the radial direction with the assembly of a pipeline into the joint body, and constituting it so as to diametrally expand the check member fitted in the circumference. CONSTITUTION:A joint body 1 has a diametral expanding chamber 4 to be provided with an elastic seal ring 5 and a bush 6, and a window hole 7 piercing through in the radial direction, and a holding member 8 with a notch 8' corresponding to this window hole 7 is externally fitted in the circumference of the joint body 1. This holding member 8 is provided with a support wall 9 engaging with a ring bulged wall P' installed a pipeline P being fitted in the coincident notch 8' and the window hole 7, and also it is fitted with a slide member 10 with a stopper wall 10' engaging with both ends of a guide groove 9' of this support wall 9. In addition, the projecting wall 12' of a check member 13 is engaged with a recess groove 11 formed in the support wall 9, through which a fact that connection of the pipeline P is properly performed is visually checked by way of expansion of this check member 13. |
