A fitting connectable to an end portion of a pipe generally includes a housing configured for receiving at least part of the end portion of the pipe into the housing, and an insert member disposed at least partly within the housing. The insert member is configured to be received at least partly within the end portion of the pipe when at least part of the end portion of the pipe is received into the housing. A retention member is movable relative to the housing for selectively connecting the fitting to the end portion of the pipe. The retention member is movable to press at least part of the end portion of the pipe radially against at least part of the insert member to help secure the fitting to the end portion of the pipe when the end portion of the pipe is received into the housing.

The fitting set forth in claim 15, wherein the retention member includes a lever having a clamp and an arm, the arm pivotally moving the clamp to engage the end portion of the pipe and apply pressure against at least part of the end portion of the pipe when at least part of the end portion of the pipe is received into the housing. 17. The fitting set forth in claim 16, wherein the housing includes an opening through which at least part of the clamp of the retention member extends to engage the end portion of the pipe when at least part of the end portion of the pipe is received into the housing. 18. The fitting set forth in claim 15, wherein the insert member and retention member are formed of a material having sufficient rigidity to deform the pipe radially against the insert member when pivoting the retention member into engagement with the pipe. 19. The fitting set forth in claim 15, wherein the retention member does not extend through the end portion of the pipe when engaging the end portion of the pipe. 20. The fitting set forth in claim 15, in combination with the pipe, wherein the pipe is formed of a flexible plastic material, and the insert member and the retention member are formed of a relatively rigid plastic material which compresses and deforms a wall of the pipe upon pivoting the retention member into engagement with the pipe. 21.
