A pipe joint unit having key members which are struck to bite the surfaces of the pipes is provided with which the pipes can easily and quickly be joined to the body of the pipe joint unit with small force, without skill and regardless of the person who drive the key member. The pipe joint unit according to the present invention includes a body of the pipe joint unit having through holes each of which faces a portion of an inserted pipe in a direction of a tangent line; and key members to be driven into the through holes, wherein each of the key members has a tapered portion which is brought into contact with the surface of the pipe in an initial stage of a driving operation and which bites the surface of the pipe as the driving operation proceeds, and a secured portion to be secured to the bitten portion.

[ What is claimed is:] [1.] A pipe joint unit for joining a pair of inserted pipes comprising:a body of said pipe joint unit having through holes each of which faces a portion of an inserted pipe in a direction along a tangent line; andseparate key members to be driven into said through holes, wherein each of said key members has a body portion that supports a securing rib member that extends from the body portion and includes, adjacent one end of the body portion, a tapered portion which is brought into contact with the surface of the pipe as the driving operation proceeds, the body portion is wider than the securing rib member and includes adjacent the other end of the body portion a contact surface that is larger than said through holes and is aligned with the securing rib member, the contact surface is susceptible to receiving a driving force, whereby the securing rib member is secured to the pipe when the contact surface is driven to a position adjacent the pipe and cannot be driven further through the hole.
