Connector for connecting spirally corrugated pipe to wall

Abstract

There is disclosed a spirally corrugated pipe-connecting connector which enables a pipe to be quite easily fixed rapidly to a handhole or the like, and maintains a sealed condition between the inside and outside of the pipe, and enables an electric cable or the like to be passed through the pipe immediately after the pipe connecting operation is completed. The connector includes a tubular connector body,including a distal end-side tubular portion,for fixing to a wall W, an outwardly-flaring, tapering portion,holding a packing member, and a spiral projection portion,which is fitted on the holder, and is threaded inversely to a spiral on a pipe P at a pitch smaller than a pitch of the spiral on the pipe P, the tubular portion, the tapering portion and the spiral projection portion being arranged sequentially in this order from the wall W toward the exterior of the wall. The connector further includes a holder,which has a spiral projection,formed on an outer peripheral surface thereof for fitting engagement with the spiral projection portion,and also has a spiral projection,formed on an inner peripheral surface thereof for fitting engagement with the spiral on the outer peripheral surface of the pipe P, and the packing member,which is adapted to be fitted on a distal end portion of the pipe P, and is disposed within the tapering portion,of the connector body
