A modular fence construction for use with a pair of posts installed in a ground mass. The posts are laterally spaced from each other and have at least one transverse support member affixed thereto. The modular fence construction comprises a plurality of pickets and at least one transverse rail affixed to the plurality of pickets. The transverse rail includes a channel adapted to receive the at least one transverse support member. The plurality of pickets and the at least one transverse rail are formed as a unitary piece and are adapted to mate with like unitary pieces to provide the modular fence construction.

An apparatus for releasably clamping an elongated flexible member is provided. This clamping apparatus includes body defining at least one passage therethrough. A clamping member is operatively associated with the body member such that a portion of the clamping member can be selectively moved into and out of the passage. Juxtaposed clamping surfaces on the clamping member and the body converge and diverge as the clamping member is moved into and out of the passage. An actuator member extends from the clamping member and is operable for causing the clamping member to move into and out of the passage to engage and disengage the flexible elongated member therein. A locking mechanism is utilized to releasably fix the clamping member in one of a plurality of engaged positions.
