A drive system for elongate members comprising a drive plate, a support system, an insertion housing, at least one drive gear, and a vibratory system. The suppression system resiliently opposes relative movement between the support plate and the insertion housing. The drive gear displaces the elongate member along its longitudinal axis. The vibratory forces are transmitted to the elongate member through the at least one drive gear. The drive gear and the vibratory system simultaneously crowd and vibrate the elongate member into the ground.

The apparatus as claimed in claim 7, wherein the second end of each first link arm is slidably mounted in the housing for movement between an advanced position in which the respective connector is aligned and positioned adjacent the other connector for connection thereto, and a retracted position in which the respective connector is axially retracted away from the other connector to permit the connectors to be disconnected. 9. The apparatus as claimed in claim 7, wherein said first connector is slidably mounted at the end of the first link arm for movement between an extended position at the end of the link arm and a retracted position spaced rearwardly from the end of the link arm, the first pivotal linkage further comprising an additional pivot link having a first end pivotally mounted in the housing, a second end comprising an additional handle, and an intermediate portion linked to said first connector for moving said first connector into said retracted position on movement of said additional handle in a predetermined direction. 10. The apparatus as claimed in claim 1, wherein the housing has a pair of end support plates adjacent opposite ends of the housing, and a pair of spaced, parallel side rails extending between the end support plates, the pivotal linkages being pivotally mounted on said side rails. 11. The apparatus as claimed in claim 10, including a plurality of support rods extending between the support plates within the housing. 12. A cable branching system, comprising: at least one elongate connector housing for releasably connecting the ends of two underwater cables together; first and second cables extending into opposite ends of the housing and having end connectors releasably connected together inside the housing; a junction box having a first set of ports and a second set of ports, and an internal routing assembly for connected any selected port of the first set to a selected port of the second set; and third and fourth cables for selectively connecting a first port of the first set to the end connector of the first cable and a second port of the first set to the end connector of the second cable when the first and second cable ends are released. 13. The system as claimed in claim 12, wherein one of said connectors comprises a plug unit of a wet mateable underwater connector and the other of said connectors comprises a receptacle unit of the underwater connector, and said third and fourth cables each have cable ends comprising a respective unit of a wet mateable underwater connector for selective releasable connection to a respective cable end of one of the first and second cables. 14. The system as claimed in claim 12, wherein said housing has a connector mounting mechanism including a first pivotal linkage for moveably mounting the first connector for movement between a first position aligned with the second connector for connecting the first and second cable ends together in line, and a second position separated from the first connector and rotated upwardly and out of the housing for allowing the first cable end to be connected to another cable, and a second pivotal linkage for moveably mounting the second connector for movement between a first position aligned with the second connector for connecting the first and second cable ends together in line, and a second position separated from the second connector and rotated upwardly and out of the housing for allowing the second cable end to be connected to another cable, the housing having an upper opening for allowing rotation of said connectors out of the housing for re-connection to said third and fourth cables. 15. A method of releasably joining cable ends and subsequently separating the cable ends and joining them into new circuits, comprising the steps of:
