The sanitary clamp of claim 1 wherein the first and second semi-circular center portions each have a groove formed therein between a pair of walls, the groove configured to receive the funnel shaped portions of the pair of connectors and an O-ring disposed between the pair of funnel shaped portions. 3. The sanitary clamp of claim 2, wherein the projection has side walls extending orthogonally from the bottom surface of the ledge, said external ratchet teeth disposed on the side walls of the projection. 4. The sanitary clamp of claim 3, wherein the external ratchet teeth are angled upward toward the bottom surface of the ledge. 5. The sanitary clamp of claim 1, further comprising: a locking knob configured to couple the projection to the first member; wherein: the locking knob extends through an aperture located in the ledge extending from the first member and includes a handle portion and a threaded portion disposed on opposing sides of the ledge. 6. The sanitary clamp of claim 5, wherein the threaded portion is configured for threaded engagement with a cavity defined by the projection in response to rotation of the handle portion of the handle. 7. The sanitary clamp of claim 6, wherein the handle portion is configured to engage the ledge while rotating such that the handle portion urges the ledge towards the housing as the threaded portion is threaded into the cavity when the projection is latched within the housing. 8. The sanitary clamp of claim 7, further comprising ratchet teeth formed on a bottom surface of the handle. 9. The sanitary clamp of claim 8, wherein the ratchet teeth on the bottom surface of the handle cooperate with a ribbed upper edge surrounding the through aperture of the first member to maintain the handle in a locked position. 10. The sanitary clamp of claim 1, wherein first portion includes a button portion extending outwardly with respect to the side wall, the button portion configured to facilitate depression of the first portion to release the engaging member from engagement with the engaged at least one of the plurality of external ratchet teeth when pressed. 11. A polymeric clamp for releasably connecting opposedly positioned terminating ends of a pair of sanitary connectors, comprising: a first member connected to a second member by a pivot connection at a first end of each of the first and second members allowing for pivoting of the first member relative to the second member between an open position and a closed position, the first and second members spaced apart to receive the terminating ends in the open position and configured to retain the terminating ends in a fluid tight relationship in the closed position; anda locking device for releasably locking second ends of the first and second members in the closed position, the locking device including a projection having a plurality of external ratchet teeth coupled to the second end of the first member and a housing defining a well on the second end of the second member configured for receiving the projection, wherein the second member includes a rocker lock having first portion, an opposed second portion including an engaging member and a flange therebetween pivotally connecting the rocker lock to a wall defining the well such that the second portion travels outwardly when the first portion is inwardly depressed, and wherein the rocker lock is configured to resiliently position the engaging member in the well to engage the at least one external ratchet tooth to latch the projection within the well and is configured to permit retraction of the engaging member with respect to the well to release the engaging member out of engagement with the at least one external ratchet tooth in response to depression of the first portion to unlatch the projection from the well. 12. The clamp of claim 11, wherein the projection is fixed to a ledge extending from the first member. 13. The clamp of claim 11, further comprising: a locking knob configured to couple the projection to the first member; wherein:the locking knob extends through an aperture defined by a ledge extending from the first member and includes a handle portion and a threaded portion disposed on opposing sides of the ledge,the threaded portion is configured for threaded engagement with a cavity defined by the projection in response to rotation of the handle portion, andthe handle portion is configured to engage the ledge while rotating such that the handle portion urges the ledge towards the housing as the threaded portion is threaded into the cavity when the projection is latched within the housing. 14. The clamp of claim 11, wherein the first and second members define a continuous annular groove in the closed position for retaining the terminating ends in a fluid tight relationship. 15. The clamp of claim 14, wherein the annular groove is at least partially defined by a pair of opposing side walls configured to retain the terminating ends in a fluid tight relationship by engaging respective flanges included in the terminating ends. 16.
